This is a terrible book. It makes no sense. The world building is horrible. The characters are fresh out of central casting. The storyline is utter tripe. The writing is barely decent. Think of the worst mishmash of dystopian YA: from Hunger Games to Matched to the Testing and Divergent and beyond. There isn't a trope in recent teen fiction that it's afraid to steal from in some mad insane way and layer onto a complete garbagefest of logic. Words fail to describe how utterly and senselessly pointless this book is. 
 Despite that, it entertained the hell out of me. 4 stars. I really liked it. But it's complete crap.
