Rating: 4/5 
 ***Minor spoilers, spoilers for book 1*** 
 (I'm writing this review from my phone so please excuse any mistakes) 
 Unfortunately, I didn't enjoy this book as much as I enjoyed The Darkest Minds. I felt like the previous book had a better feel of mystery and suspense. While this book was definitely great, it didn't get at me the same way the first one did. 
 This book begins several months after what took place at the end of book one. Ruby is with the League running Ops with them. Except, the League isn't as it should be. There are people on the inside who are looking to get rid of the "problem" - the children, the Psi. When Liam's brother, Cole, reveals to Ruby that they might be able to win the battle on the inside with intel that could take down the government, she's ready to do what it takes. Except, succeeding in their mission requires finding the boy whose memories Ruby erased - Liam. 
 I kind of felt that Bracken didn't exactly think it through when she decided that Liam would lose his memories of Ruby. (view spoiler)[ I found it really underwhelming how Liam got his memories back. It seemed like the author couldn't magic up a better way and this way the only way she could think of. (hide spoiler)] Thankfully, that was pretty much my only major problem with this book. 
 In this book we're reunited with some characters, Chubs and Liam. (I really wanted Zu to make an appearance, but no luck.) Some other familiar characters also make an appearance later on in the book. It was also great meeting some new faces from the League. I found the character development great, and it was interesting to see how Ruby changed throughout the book. She develops a lot in both her abilities and her personality. I did feel like we didn't get enough Liam, though. 
 This book didn't drag in the middle for me like the first book did, but it also didn't have the amazing ending that we were delivered in The Darkest Minds. While I felt like this book was strong throughout, it just seemed like SOMETHING was missing to make it as great as the first. 
 Overall, I found this a great read but I didn't think it was as good as the first one. If you enjoyed The Darkest Minds, I think you'll definitely enjoy this one as well. This is a strong series and if you haven't yet picked up The Darkest Minds, get to it!
