It's odd, but despite how many zombie stories I've read over the years, the only Joe McKinney zombie story I'd read was the one in The Living Dead 2, until I got a review copy of Dead World Resurrection.This is obviously going to have to change, as I enjoyed the collection and will now have to get the novels in his Dead World series.
There are some really good stories in this anthology, but there were also some things I didn't care for all that much. There were a couple of short essay-ish pieces, namely "Zombies and Their Haunts" and "Suburbia of the Dead," which would have been better off excluded as they were kind of boring and were reused in the lengthy "A Reader's Guide to Dead World" at the end of the book.
The actual short stories were pretty good, and reasonably diverse for zombie stories. Many of the stories feature the viral zombies of the Dead World series, but despite the title, not all of the stories are do. "Sabbatical in the Ohio Methlands" has zombies that are zombies in a more metaphorical sense.The zombies of "Starvation Army" seem to be more like hungry ghosts. "Jimmy Finder" has zombie-fighting robots. There are even stories where people become zombies from ODing on psychedelic mushrooms or from cuts caused by strange clams.
This is a really good collection of zombies stories that's far better than the formulaic crap that seems to have flooded the market in recent years.
