I really dig this book. Like... a lot. A murder mystery? Sociopaths? Teens thrown together under questionable circumstances? Yes. Yes. Yes. Oh and there's a cult. I loved how the secondary characters were fleshed out and the entire premise. Our main character, Signal, feels a little emotionally stunted for her age, but being a loner and then being in prison can do that to a person. My biggest complaint was the rather abrupt ending. I was hoping for big government conspiracies and... well... more... If this happens to have a companion novel later, I'll definitely read it.

&nbsp; I want to start out by saying my problems with this book were mostly just my own personal issues and that most people will probably like this book just fine. Also my low rating does not mean this was a bad book it just wasn&apos;t a book for me.<br>
&nbsp; I think the main thing this book suffers from is it tried to fit to much into one book and so nothing felt completely fleshed out. The characters all seemed to be pretty flat or not individualized enough. I spent a good portion of this book forgetting who was who because they all felt the same. We didn&apos;t get much of a back story for any of them and what we did get was so generic it did nothing to actually flesh out the characters.<br>
&nbsp; Secondly none of these characters felt realistic as &quot;class A&quot; killers. They had way to many emotions for being psychopaths or lacking empathy. There was no deference from the killers to the main character making it all feel very shallow and fake. <br>
&nbsp; I also hated the love triangle Sparks tried to incorporate. It again turned what could have been a great dark twisted book into just another shallow boring YA novel. She had such an amazing concept that if she had really focused on she could have written an amazing YA horror/thriller but she wasted it on a sloppy love tried and boring meandering characters. <br>
&nbsp; The only thing that really saved this book for me was the last five chapters or so when we got a few answers. I enjoyed those last chapters so much more. If the rest of the book had been that intensive I would have given this a much higher rating.<br>
&nbsp; I also just want to take a quick aside to say quit having characters claim to be gay or queer to avoid being with a character! Its played out and extremely offensive to the queer community! We are not an identity for your characters to hide behind! I am so sick of seeing that! Its disgusting that I need to point this out in 2020!
