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.
