Written by an American, and not a whole lot that seemed specifically Canadian about this one (other than one crack about some of the characters being "pale even for Canadian kids" after being badly frightened), but the bulk of the action supposedly takes place in Thunder Bay, Ontario. The forthcoming sequel appears to be set there also.
Teenager Theseus Cassio Lowood is carrying on his father's family business: ridding the world of murderous ghosts. He and his mother move frequently as Cas dispatches one opponent after another. When they arrive in Thunder Bay, Anna Korlov, nicknamed "Anna Dressed in Blood", turns Cas's world upside down: he can't understand why she is so powerful and why she doesn't want to kill him.
