What Is This Book Called?

Okay so the book is small. Meaning, it's not very tall but it's slightly think. (Maybe 400+ pages) On the cover, there's a diving board and I think you can see a pool. The border on the book is white and the title is short. (It might be like 1-3 words only) The book is about a teen guy who drinks, does drugs, has a bunch of sex, and watches porn. I think there might be a second book - but I do know I saw a second book by that same author. I always see the book at Barnes and Noble and I want to read it but I can never remember what it's called. Sorry for the crappy description. Thanks in advance. (: <3
