How do you send a killer to the grave when he’s already dead? Having narrowly averted an (under)World War, Cat Crawfield wants nothing more than a little downtime with her vampire husband, Bones. Unfortunately, her gift from New Orleans’s voodoo queen just keeps on giving—leading to a personal favor that sends them into battle once again, this time against a villainous spirit.

Centuries ago, Heinrich Kramer was a witch hunter. Now, every All Hallows Eve, he takes physical form to torture innocent women before burning them alive. This year, however, a determined Cat and Bones must risk all to send him back to the other side of eternity—forever. But one wrong step and they’ll be digging their own graves.

It's a tough life for witch Rachel Morgan, sexy, independent bounty hunter, prowling the darkest shadows of downtown Cincinnati for criminal creatures of the night. She can handle the leather-clad vamps and even tangle with a cunning demon or two. But a serial killer who feeds on the experts in the most dangerous kind of black magic is definitely pressing the limits.

Confronting an ancient, implacable evil is more than just child's play -- and this time, Rachel will be lucky to escape with her very soul.
