3.5 stars for what this book could've been. 
 Now, I'm not an experienced reviewer but I'll try my best to explain why I loved and hated this book. 
 First, ( IN MY OPINION) the theme with (view spoiler)[ pain/ needing pain, (hide spoiler)] it's getting old and it only make me to roll my eyes and ask myself "why the hell did I bought this book?". 
 Ok, I get it this book kinkiness it's different, but it's still confused me. And it did because I never expected it. 
 Second, I lost most of the interest in this book when Georgie went United States of Tara and had me scratching my head and ask myself again "What the fuck is this?" 
 But you see, I didn't completely hate it. 
 I liked the my-brother-best-friend touch, I like it how Georgie "tortured" Deck with her bold words and endless flirting, and I loved the intensity of their feelings. It made it believable since they knew each other for a long time. I could totally buy this. 
 What I could never buy, and had my BS meter go over scale, was how immature Georgie appeared to be on the second part of the book, opposite to how she appeared to be in the first part. Perfectly composed and with an interesting agenda . And the organization? I mean, man... why couldn't this be simpler? More "real"? 
 Either way, I'm still reading the next book. 
 I'm curious how Kai's gonna handle his story, and if I get to see another heroine with multiple personalities. 
 Overall, Perfect Chaos was a decent read. A touch of madness here, some kinkiness there, it worked for me, hence the 3.5 stars.
