My good friend (and collaborator on a story we may yet finish someday) Derryl Murphy has a short story collection just out from Wildside Press, Wasps at the Speed of Sound. I've read many of the stories in the book already, and I recommend them unreservedly.

In his blog he lists a lot of places you buy the book, but if you want the hardcover and are a Barnes & Noble Readers' Advantage member, I will point out that you can save three bucks through them.
