James Patterson, i like the way the chapters are a few pages long, its much easier to read and more biteable if you get what i mean, um his books are kiss the girls, along came a spider, midnight club, etc. theyre pretty good as most of them you find out the killer/story in the last 2-3 pages.
I'm a huge fan of the Death comics by Neil Gaiman!
Also, it's not really a "book", but if you haven't already, check out Preacher. It's a crazy messed up comic, amazing story and kick-ass art. Definitely not a children's comic.
The Death of Hitler..brilliant book that investigates hitlers last days in the bunger before he offed himself, and used never before released Russian KGB files to back up everthing that is said in the book..must read for any history/war type buff
