Cas Lowood is a ghost hunter first and foremost. It is a gift Cas inherited from his father, along with his deadly athame, when Cas was 14, seven years after dad died on the job. Now Cas, 17, and his witch mother travel all over North America following tips on ghosts that need taken care of. Cas isn't worried about school, he isn't worried about friends, and he definitely isn't worried about love. Until, of course, he follows a tip to Thunder Bay, Ontario to take on the ghost locals call Anna Dressed in Blood.
I enjoyed this book, but I thought it left a lot of the mythology unexplained. Now I see that it's the first in a series, so I guess I'll find out more next time.
