"The Hour I First Believed" by Wally Lamb is fantastic and really long (I think that's a bonus since it takes longer to read

). Any of his books are really good. I read tons of books so I buy a lot of them used. I get most from half.com or amazon. Just make sure the seller has a good feedback rating. I've never had any problems.
I just finished Dennis LeHanne's "Shutter Island". Really, really, REALLY amazing! I could read it again already

. I'll be buying or borrowing all of his other books soon.
I read many different genres but I don't like historical fiction or romance novels. I do read some chick-lit though occasionally to break up my thriller habit
