This is a mature book that deals frankly with sexuality. Therefore, I would not recommend it for younger readers without parental consent.
That said, I feel for the people in this book as if they are real, breathing human beings. No one is perfect; everyone is trying to get by as best they can. The urban feel of the book is gritty, although it is less harsh than Tyrell, the other book by Booth that I've read. (There is one section at the very end of the book where Booth refers to Tyrell, and people who haven't read the other book might wonder why the heck she's mentioning this dude. That was the only stretch for me, though). What I like most about this book is that even minor characters seem to have their own lives outside of their relation to Kendra-- the protagonist. They have motivations and needs that are separate from hers, and, after seeing too many cardboard sidekicks and extras in novels, that is refreshing.
