Hmm. I was kind of mixed about this book. I was sucked in by the flowers' horrible plight, and I kept turning the pages (well, virtual pages-I read it on the Wattpad app) until the end. I felt horrible for them because Colin was a terrible person, and hoped that they would escape soon. 
 But the rest of it kind of fizzled out from my fingers. Summer's family was unbelievably stupid (a trait that runs in the family, I learned while reading the sequel...but that's a rant for another time) and seemed to do nothing in the investigation. Meanwhile, Summer's uber-dedicated boyfriend runs all over town trying to find his lost girlfriend. All we see is how we think a boyfriend should act-angry, protective, and tirelessly working to save his girl-but no other emotions. I think it would have been more interesting to follow his investigation with more real emotions, instead of...plastic ones. You know? 
 And speaking of plastic, I hated the ending. Something about how she ran into Lewis' arms instead of her family's really irked me. Plus, how can she be so "back to normal" so soon. She was trapped in a cellar and attacked for months! How can she be all Pollyanna happy mere weeks after such terrible things were happening to her? (view spoiler)[ Also, what the hell was up with the cliffhanger ending? People don't just escape from supermax prisons, especially not somewhat dull-witted criminals like Colin. (hide spoiler)] 
 I understand that the published version is different than the one online, so I might rent that one from OverDrive one day. But for now, I'll have to pass. 
 As a final thought, I'd like to add...a white van? Really?
