Just finishing up World War Z.

Highly recommended. If you like zombies, you'll love this. However, if you like zombies, there's a good chance you've already read it. They're making a movie out of it, and I don't see how they can do it with a book written as a series of interviews...I guess...they could do a series of interviews.
The Zombie Survival Guide was good, but this was far better, I thought.
My dad suggested Jack Reacher series by Lee Child. Anyone read any of it?
Also, I suppose graphic novels are fair game. Watchmen and V for Vendetta: recommended. Both are better than their movie versions. It's been a while since I read it, but I recall enjoying the Rising Stars series.
On my to read list:
Flim-Flam! Psychics, ESP, Unicorns and Other Delusions by James Randi
Lush Life by Richard Price
Zombie Spaceship Wasteland by Patton Oswalt
The Last Christmas by Brian Posehn and Gerry Duggan and Rick Remender (graphic novel)
Batman:The Killing Joke by Alan Moore and Brian Bolland (graphic novel)
