This summer reading list from Changing Hands Bookstore owner Cindy Dach is very good. I found it on http://www.azcentral.com/
"Zone One" by Colson Whitehead. The thinking-person's zombie novel. This takes place in aftermath of a zombie plague in lower Manhattan which has been scheduled for human resettlement. Whitehead's writing is astounding and he brings the world of the undead vibrantly to life.
