Undead and Unwed by Mary Janice Davidson (2004)

Young, single girl who loves shopping gets hit by a car and wakes up in the morgue as a vampire. Oh, not just a vampire, but the vampire queen.  Very funny chick lit, very untraditional vampire story. An enjoyable, fun read and set in Minnesota, no less!  Continued for many, many volumes, but as I don't really like long-running series, I can't attest to more recent volumes.
