 So I think I will probably remember the last book in The 5th Wave trilogy better than I remembered the 2nd book, Infinite Sea. I ended up having to visit a website to get a summary of the entire story so I could make the connections between some of the things I read in this one compared to what I remember from Infinite Sea. In fact, after reading the summary, I still couldn't remember some of the larger events from the ending. Was it really that unmemorable? This one was definitely close in the memory catalog. 
 It took me over two weeks to read this short(ish) book and it really shouldn't have. I still enjoyed the characters, but felt like this book (like the previous one) tried to "do it all". This book is plot driven - and it should be! I think that was reason I liked The 5th Wave so much. It was for the most part, action packed with chapters ending with a character getting into a sticky situation and then switching to a new character. It kept you wanting to read and find out what was going to happen to that character, which required you to get through your current chapter. Looking through my review for Infinite Sea, I can tell that I felt the same way for that one (even if I don't remember it) as I do for this one. THERE WAS TOO MUCH! The author, while trying to pack with action (we were on a time limit of 4 days) also tried to pack in character development which ended up leaving me wanting to skip over full paragraphs (and sometimes pages) of the thoughts running through characters' heads. I really don't care what you thought right before you pulled the trigger to kill yet another person who really doesn't mean much to you in the grand scheme of things. I was starting to find Cassie's internal dialogue irritating and overly dramatic - and yes I realize she is a teenage girl. 
 That aside, I did enjoy seeing a few characters finally step up and/or follow through and overcome whatever their obstacles (all mental obviously) might be. 
 The ending was also a matter of contention for me. I understand what everything happened in the way that it did, but partially wish Evan would have died as well. It would have made Cassie's death feel slightly more poetic and rich. To me, this felt like another Tris death in Allegiant. And I was left pissed off at the end of that book. At least I don't feel pissed off for this one. But seriously... what is Evan's purpose now? He's more of less become a shell because Cassie died anyway. Grrr.. 
 And plot hole... how the hell did Ringer/Marika's baby make it when she was beaten bloody and broken by Evan in his "shark" mode rampage?! I don't care if you have the rib cage of the strongest whale, you can't attribute the 12th system for keeping her baby alive. You aren't left with a broken back, and other broken bones (literally everywhere in your body) and not end up with some kind of puncture somewhere internal around your pelvis. Your brain may have shut down pain sensors, but that doesn't mean that you haven't been hurt.... Baby should not have survived... Unless she and Zombie/Ben made a new baby. And if so, it's about time! 
 Overall, I was disappointed and am left feeling like I shouldn't have chosen to go on with this series after book one.
