If you’re looking for an anthology of stories that mix urban
fantasy (of the magic & witches kind) with hard core noir detective work
then Down These Strange Streets is the anthology for you. The
anthology, edited by George R. R. Martin and Gardner Dozois, features stories
from Charlaine Harris, Patricia Briggs, Diana Gabaldon, and Simon R. Green
among others. I always like a good
anthology because even if you don’t like one of the stories odds are good
you’ll like another so you can count on getting something out of the book.
