War for the Oaks

A fantasy novel by Emma Bull and one of the pioneering works of Urban Fantasy, War for the Oaks is the story of Eddi McCandry, a Minneapolis rock singer who's just been kicked out of her band and breaking up with her boyfriend. There's also the matter of The Fair Folk moving in—quite literally—with her, and an impending war between the Seelie and Unseelie Courts into which she's just been drafted.
