How do you rid the Earth of seven billion humans?

Rid the humans of their humanity.

Surviving the first four waves was nearly impossible. Now Cassie Sullivan finds herself in a new world, a world in which the fundamental trust that binds us together is gone. As the 5th Wave rolls across the landscape, Cassie, Ben, and Ringer are forced to confront the Others’ ultimate goal: the extermination of the human race. Cassie and her friends haven’t seen the depths to which the Others will sink, nor have the Others seen the heights to which humanity will rise, in the ultimate battle between life and death, hope and despair, love and hate.


That’s the cost. That’s the price. Get ready, because when you crush the humanity out of humans, you’re left with humans with no humanity.

In other words, you get what you pay for.

The sequel to the much-hyped about The Fifth Wave leaves me with feelings similar to those I had at the end of the first book: feelings of confusion, and, overall, a general sense of mediocrity. I felt a bit disconnected to both books and, while I still appreciate them as stories, I am struggling to understand the hype.

The Infinite Sea starts exactly where The Fifth Wave leaves off – Cassie, Ben, Ringer and the rest of the crew are now residing in an empty hotel, waiting for Evan’s return…provided he’s still alive. But the longer they wait with no sign from him, the more they’re forced to realize what they’re up against.

The Infinite Sea is just as action-packed and thrilling as its predecessor; giving you no time to glance up from the pages or breathe. There are shocking twists, turns and revelations about the alien’s true motives (more on that later); all leading up to the expected killer ending. For those who want more romance, I can’t say you’ll find it here because that is definitely not the focus of the story; but the few romantic interactions there are were definitely well-written.

As with The Fifth Wave, The Infinite Sea is also narrated in multiple perspectives, which really allowed us to get into the character’s heads and let us truly get to know them; and I found each perspective well-executed and exquisitely written.

Cassie doesn’t play as big of a role in this novel as would be expected, considering she’s the protagonist. (Not that this bothered me much, because I found her to be a bit annoying here with her obsession with Evan).

No, fortunately, the focus has shifted, and the star here is Ringer. The entire second half of the story is told completely through Ringer’s perspective, and it was absolutely fantastic. She’s fierce, serious, and blinded by rage; but I absolutely loved her. I can’t wait to see more of her in the third installment and to watch her story expand.

My biggest problem with the novel was the reveal of the alien’s motives. It may just be my lack of intelligence, but even when it was revealed why the aliens took over the Earth and killed all these people, the explanation was a bit complex and hard to understand.


I wish it had been a little more direct and comprehensible, because I still don’t quite understand why they did what they did.

Nonetheless, I am interested in seeing how this spans out and how everything resolves. A very decent sequel despite its flaws, so if you enjoyed the first installment, definitely give this a try as well.


45 thoughts on “The Infinite Sea

  1. I really want to read this series but there have been so many so so reviews on it lately that I really don’t at the same time. I am afraid that I will be disappointed. Maybe if I go into it with little expectations I will be okay.

  2. Hm, this bums me out. I felt like you did with The 5th Wave, very “meh”. It felt so heavy, and not in a good, emotional way. Just unnecessary. Like it could have been written in far fewer words, and all the excess left me quite underwhelmed. I didn’t even bother to review it, because I didn’t know what to say other than that! I was hoping that this one would be better, and I do still plan on reading it, but I am glad I know what I am heading into now! Great review!

    1. I am so glad to find someone who feels the same way Shannon! I agree – it felt like Yancy was trying to throw some philosophy in there, but it just…didn’t work, you know? I’m interested in seeing what you think about this once you finish it.

  3. I haven’t read either book, but I’ve heard the sequel isn’t as good. Maybe they liked Cassie? Ringer sounds more my style. I like that there’s not much romance, the world is ending after all. I hope there will be more explanation in the conclusion. I’m getting the first book soon, but I’m tempted to wait for all three since it’s to be continued again. Nice review. 🙂

    1. To be honest, I’m not sure if I prefer the first or second book more, because both had their pros and cons. But I definitely felt like it was smart of Yancy to shift his focus to Ringer because she’s a much stronger character than Cassie IMO. 🙂 Thank you!

  4. I haven’t read either book but truthfully I have no wanting to. I didn’t hear great things about The Fifth Wave, and I haven’t been hearing great things about The Infinite Sea either. I know I should just pick it up and at least TRY it, but I can’t find it in me to do that. 🙁 Great review, though! I can totally understand why you thought it felt a bit…mediocre.

    1. Thank you Sydney! I completely understand your worry. I’d definitely say to at least try the first book and go from there probably. 😀

  5. I actually quite enjoyed the first in the series. I remember seeing quite a lot of mixed reviews for it, but I personally felt like it was a breath of fresh air compared to other YA post-apocalypse novels I’d read at the time. But, in saying that, I’m not super excited for this one. I know I’ll read it eventually, but it’s not high on my TBR list. Thanks for the honest review! 🙂

    1. I’m so glad you enjoyed the first installment so much Kara, and I can’t wait to see your thoughts on the second when you read it. 🙂 Thank you for the lovely comment! 😀

  6. Wonderful review, Zoe! I do want to read this, but I’m in no hurry to. I read the first book at the beginning of the year and enjoyed it, but found it a little dense. I’m glad that this is a shorter book and still full of action, but I’m sorry to hear that Cassie doesn’t play a big of a role in this novel.

    1. Thanks Ebony! 😀 I had the same feeling about the first one – it was a decent novel, but all the philosophy in the writing annoyed me too.

  7. I hated The 5th wave, so I’m not planning to read this book. I don’t even remember half of what happened :’) Cassie annoyed me SO MUCH, it sounds good that she doesn’t play a huge role, haha. I’m going to hunt down spoilers around that twist, because like I said, I don’t want to read this one. I’m only curious to see what you are talking about.

    1. If you weren’t a fan of the Fifth Wave, I doubt you’d like this one then – ha! If you don’t like Cassie, this one will probably be better for you, but I’d definitely understand if you skip it because of how you felt about the first one.

      And here: [spoiler]The big twist is that the aliens aren’t actually aliens, they’re modified humans…[/spoiler]

  8. I felt mediocre about the first book as well, and so do not have high hopes for this sequel. Glad to see you agree with me, though I was hopeful the book would be better since the premise is so interesting. I’ll probably read it some day, but I’m not in a hurry.

    1. If you had a mediocre experience with the first one, you’ll probably feel the same way about this one unfortunately. 🙁 Putting it at the bottom/middle of your TBR is probably a good plan though! 😀

  9. HIGH FIVE, ZOE! We literally have the exact same thoughts about this one.I couldn’t help but feel like it was a completely mediocre book at the end. I was left saying “that’s it? I waited for this?” Which is super unfortunate because I was so prepared to give it some love (plus the hoops and loops I had to jump through to actually get the book was tiresome). I was so confused by that explanation at the end because I thought we all knew that that was the reason anyway. For some reason, I was already reading this book with that reason in mind and I just thought it was all common knowledge. But perhaps not since that was the big reveal we all worked up for. Hmmm…I still have hopes for the sequel because the writing was amazing! Fantastic review, as always, Zoe!! <333

    1. YEAH! Twinsies! 😉 And I completely agree Jess. At the end, I was really just confused because the alien’s motivations were written in such a philosophical way that I never really understood it. But the twist about [spoiler]the aliens not actually being aliens[/spoiler] was definitely better. Thank you!

  10. Your review made me laugh HAHA I don’t even think I should give this a shot. I feel like it’ll just annoy the hell out of me. I have a hard time loving alien books hehe so…aliens are just plain weird. The only book I enjoyed about aliens is the Lux Series. HAHA

      If you’re not a fan of alien books, this series in general probably wouldn’t be for you.

  11. Hmmm, I’ve heard a lot of variable reviews about this series as well which is why I’ve taken so long to pick it up. Cassie sounds really annoying and an obsession with a guy? Yeah no thanks. I do like the sound of Ringer though, she sounds like a really fiesty and interesting one! That would be interesting to read. I need to read this series still, thanks for the honest review Zoe!

    1. I completely understand Jeann! Cassie is definitely an annoying protagonist unfortunately, but luckily she doesn’t feature much in this book (not sure why…) and Ringer takes the stage, which made me really happy. Thank you for the lovely comment Jeann! <3

  12. My friend said he was reading it and he didn’t know who was narrating at all! That’s weird, though, that the attention would shift away from Cassie, but then, she’s still obsessed over Evan? Like why? Ugh, the story was captivating in The 5th Wave but the romance could have me grimacing.

    I’m excited to read it, though, but I hope it’s still just as good as The 5th Wave was, story-wise.

    1. That was one of my problems with it too. The book is written in third person, so there’s nothing to distinguish one character from another in terms of perspectives; and, unfortunately. And I know! Ugh…the love triangle here was definitely annoying! If you liked the story / characters in The Fifth Wave (especially Ringer), I have a feeling you’d like this one too.

  13. HI ZOE

    I skimmed the review a little because I haven’t even read the Fifth Wave yet! But I’m glad you did like the sequel, I don’t know if I caught this, but was the first book better? I’m not a fan of being confused, unless I have someone to talk to afterwards about it!


    1. In terms of which one was better, I honestly don’t know. They both have different pros and cons that level out to be about the same, so it’s hard to say. Character-wise, this was much better; but in terms of the story I’d have to say the first one was better.

  14. Darn. This scared me. Do I have to be intelligent to understand the alien’s motive? I’m not too good at understanding complex and scientific explanations so I hope I get through this.

    And isn’t it so sad that the hype machine isn’t always accurate? The 5th Wave wasn’t even great for me but I want to see what happens next so I still want to read The Infinite Sea.

    1. Unfortunately, I think you do… Their motives are very philosophical and didn’t really make sense to me, so I’m interested in seeing what you think when you read it.

      And yeah…it’s so sad. 🙁 If you were a bit meh about The Fifth Wave like I was, I wonder how you’d feel about this.

  15. Yeah, I kind of liked that Cassie wasn’t that prominent too. All she did was whine about Evan, and that was a big no-no for me. Ringer was AMAZING as a heroine (or anti-heroine?) and her story took such an awesome turn and AHH. I can’t wait to see where it goes.

    I get what you mean abut the reveal . . . like, what? It’s all a bit convoluted at this point. But that being said, I’m in this for the characters, so I can look past it.

    I definitely need more Ben in book 3 though!

    1. I’m glad you felt the same way Allie! 😀 I definitely thought the focus on Ringer was fantastic too. 🙂

      And yes! BEN = :heart:

  16. LOL Girl I’m sure that Sheldon himself would be confused with the lack of reasons and that’s one the issues I had with the first book. I’m so sad it never got solved here either so I’ll be skipping this one and leaving this series behind. Still amazing review, Zoe 🙂

  17. I’m really excited about this one and even with the negative aspects you pointed out I’m suuuuper curious! I’m dying to know the motive of the aliens and excited that we find out in this book even if I may not like the motive itself lol. I also am intrigued that the MC has seemed to switch to Ringer! Great review, hun! 🙂

    1. I’m interested to see what you think of this one Giselle since we have such similar opinions on books in general. Thank you! <3

  18. Well, this is kind of disappointing. O_O

    I haven’t read The 5th Wave yet, but I have pretty high expectations for it due to all the hype it’s been getting. Now I’m afraid that I’ll find it mediocre, too, which is a really high possibility, considering I’m probably one of the fussiest readers around. >< So in that sense I kind of understand why you found the sequel to be a bit of a letdown! Sequels are hard to pull off, though — especially second books. :/

    SO curious about the aliens' motives. And yeah, science-fiction books tend to have the risk of going overboard with the complexity, so I'm not too surprised that the explanation turned out to be so complicated. *cough* Parasite *cough* I probably will have a tough time understanding it too; science REALLY isn't my strongest subject, lol. xD

    So sorry this wasn't as great as you expected, Zoe, but brilliant review all the same! (I had to skim through real quick, though, just in case there were spoilers. :P)

    1. *sighs* I was meh about the first one too, so I didn’t really know what to expect from this in the first place. As for the reveal, it’s not even that it’s science (it’s actually not science-y at all; it’s more philosophical than anything), but I didn’t understand it at all. 🙁

      Thank you! <3

  19. I loved this one Zoe, but couldn’t agree more with your assessment about Cassie. Bloody hell, she was like a forlorn teen pining away for a lost love. Hello? World ending anyone? Thank goodness for Ringer! I didn’t really connect with her in book one, but in TIS, she was fierce. I’m really hoping book three continues on with Ringer’s point of view, I’ve got a girl crush that’s for sure. She’s epic.

    LOVED the review Z (trying out a new nickname), brilliant! <3

    1. …She was like a forlorn teen pining away for a lost love. Hello? World ending anyone?

      OMG – exactly! <3 And ha! I felt the same about Ringer. I love characters who are fierce and strategical, and she definitely fits that bill. 😀

      Thank you! (And love the nickname too!)

  20. Brilliant review, as always, Zoe! I’ve recently scheduled my reviews for this and the first book. My feelings were similar. I didn’t really understand the complete explanation that was given. When the people came up with their own idea, with the rats, that made sense. When they said you wouldn’t want to move into a house that was filled with rats. You’d exterminate the rats first. I got that explanation, haha. I was kind of on the aliens side then.

    Evan was a character I really didn’t get in the first book. He was just so weird and creepy. And Cassie changed a lot once he came into the picture, which was really frustrating. With the sequel, I just wanted Evan to stay away.

    I was glad when we switched to Ringer, she was a lot easier to follow. She was actually tough and everything I was hoping Cassie would be when I first started The 5th Wave. I’ll still continue the series, but I’m not sold on the series. I honestly don’t get the massive hype that surrounds it. The books are okay, but they have a lot of issues.
