I've just picked up a new book from town today, it's by the author Kim Harrison.

It's the second in a series of books centred around a character called Rachel Morgan. The first book was called Dead Witch Walking, this one is called The Good, The Bad And The Undead.

Has anyone heard of/ read these books?

Sounds familiar but its not a book I've read personally. I like the title though, sounds post apocalyptic.
