War for the Oaks (Emma Bull)
Amazon.com Description
Eddi McCandry sings rock and roll. But her boyfriend just dumped her, her band just broke up, and life could hardly be worse. Then, walking home through downtown Minneapolis on a dark night, she finds herself drafted into an invisible war between the faerie folk. Now, more than her own survival is at risk—and her own preferences, musical and personal, are very much beside the point.
But it is more than the traitorous intrigues of villains that threaten Cazaril and the Royesse Iselle here, for a sinister curse hangs like a sword over the entire blighted House of Chalion. And only by employing the darkest, most forbidden of magics can Cazaril hope to protect his royal charge -- an act that will mark him as a tool of the miraculous . . . and trap him in a lethal maze of demonic paradox.
