This book was well written and easy to read, but it annoyed me on many levels. Cam, our hero, is very angsty and has pulled away from his family for pretty much forever. I didn't feel like the reason for this withdrawl, when it finally came out justified his behavior. (view spoiler)[ It was because he was a middle child? And he felt lost in his family and didn't want to let them down, so it was easier just to withdraw? (hide spoiler)] 
 He is an ass to Chloe early on in the book, and I don't know that I ever forgave him for the deliberately cruel comments he made to her. His actions after this (view spoiler)[ when Chloe loses her short term memory of this awful conversation between the two of them, Cam pursues a relationship with her, partially motivated by guilt, but never tells her what happened between them (hide spoiler)] made me madder. He had many opportunities to set things right, but I wasn't happy with how he handled things. 
 There were things I liked - especially Chloe's terms for the summer fling they decide to have. It was really original and had a lot of promise, but, honestly, I was so frustrated with Cam, I just didn't enjoy it. 
 I was also a little puzzled with the choice of the author to described explicitly the kissing and groping sessions between Cam and Chloe, and even let us see a discussion about condoms, but then fade to black when they actually had sex. And they had sex a lot, so it was jarring for me. 
 I think this book might work for someone else, but it just didn't work for me.
