A big heaping helping of zombies, as the editor explains :
"In the process of assembling this anthology, I read more zombie stories than you could possibly imagine, and I found more good ones than could possibly fit in one volume, even a mammoth tome like this one. So, in order to help narrow down my selections, I created a few loose guidelines for myself. First, I wanted to avoid taking too many stories from any one source. Second, I wanted to avoid taking too many stories from other zombie anthologies. I discovered a lot of great zombie fiction elsewhere and thought that this book would be more valuable to zombie fans if it were to collect that material."
That is, he wanted to mostly avoid stories you could already get in other zombie anthologies. So there's a variety here, science fiction zombies, non-horror zombies, the origins of Anita Blake, vampire slayer and necromancer and the odd story with no zombies at all that will likely annoy some - and are usually among the weakest stuff, too.
So there's an intro, an introduction to each story, but no zombie bibliography or other reading or viewing lists like in Wastelands. So I suppose this is 'another zombie anthology' as opposed to a retrospective study approach.
Still rather good though, I'd call it a 4.25 rounded up.
