World War Z is the only one I know of. Hardly new, and doubt that you haven't read it, but... just in case you missed it.

an expert on zombie theme, ceridwen!
speaking of zombies, I started 'Walking Dead' series some days ago!

Although i'm a big fan of the book, I think it's unfair to call it a Zombie book as it hardly has any of the stereotypical flesh eating "BRAINS!" Zombies in it.
