The book moves on past Johnny's awkward youth, and the rest of the book is honestly a lot better.
Johnny becomes an even more dislikeable person, though. While he was young, his self-centredness and awkwardness seemed plausible; once he was a man verging on his forties, I found Johnny's cowardice contemptible - any sympathy I had for the teenage Johnny's issues immediately disappeared, especially when the nearly-forty-year-old man starts fantasising, again, about 17-year-olds. But it's a lot less cool when the character isn't 17 himself any more.
As a woman in her mid-twenties, I'm probably the wrong demographic for this book. It disgusted me instead of intriguing me, and I got bored where I was probably meant to feel suspense. I'm not sure what the right demographic would be - possibly a single man who has wasted his life to date and wants to read about a peer.
I wouldn't recommend this book to anyone, though. The main character is utterly unlikeable, and the book was wholly depressing.
