Do you crave adventure? How about one where your enemies are killer ghosts? That's exactly what happens in the book "Anna Dressed in Blood" by Kendra Blake.
Cas Lowood is extremely good at one thing: killing ghosts. Inherited from his father, this ability lets him kill ghosts with the use of a special knife.
As he travels around the world, he gets a tip about a famous ghost in a local town that goes by the name "Anna Dressed in Blood" who has been killing people who wandered into her house for almost half a century now.
Cas is interested in Anna-and not only just to kill her.
