This is a great zombie anthology, but I think it would be best read in little chunks every few days or so. I read it all through in one big rush and was completely zombied out by the end. I was afraid that when I started my next book I would be expecting zombies to come shambling into the story at any moment. My favorite story was "This Year's Class Picture" by Dan Simmons, followed by "Calcutta: Lord of Nerves" by Poppy Z. Brite and "Bitter Grounds" by Neil Gaiman. I enjoyed the varying takes on zombies and the way the walking corpses could be transformed into sex objects, food, pets, political symbols and servants. (Though I wasn't a big fan of the stories that did make them political pawns. I guess I just don't get why the undead would care too much about politics.)
I am really looking forward to the other collections of stories John Joseph Adams has edited.
