Godless by Shayne Silvers — book slip

Callie Penrose is back to murder vampires and chew bubblegum. And she's all out of bubblegum. After discovering she has a Godfather, Callie learns that the future of the world depends on them taking an immediate road trip to Castle Dracula.

This mythical place, believed to be abandoned after Dracula's supposed death, is very much alive. Dracula has secretly been running the Sanguine Council, the governing body of every vampire in the world.

Callie's mission is to assassinate Dracula, but she soon discovers that he is the least of her concerns. Some bonds should never be forged, as once made, they can never be broken.

Callie is about to show the world fear in a palmful of blood.

For fans of Jim Butcher and Kevin Hearne.
