Shadowspell: Faeriewalker

On top of spending most of her time in a bunkerlike safe house and having her dates hijacked by a formidable Fae bodyguard, Faeriewalker Dana Hathaway is in for some more bad news: the Erlking and his pack of murderous minions known as the Wild Hunt have descended upon Avalon. With his homicidal appetite and immortal powers, the Erlking has long been the nightmare of the Fae realm. A fragile treaty with the Faerie Queen, sealed with a mysterious spell, is the one thing that keeps him from hunting unchecked in Avalon, the only place on Earth where humans and Fae live together. Which means Dana's in trouble, since it's common knowledge that the Faerie Queen wants her and her rare Faeriewalker powers dead. The smoldering, sexy Erlking's got his sights set on Dana, but does he only seek to kill her, or does he have something much darker in mind?"
