Mystwalker, book 1: The Trouble with FateLeigh Evans2012

WHAT SHE DOESN'T KNOW MIGHT KILL HER: Hedi looks normal. Yet that's taken effort. Her fellow Starbucks baristas don't see her pointed ears, fae amulet or her dark past, and normal is hard for a half-fae, half-werewolf on the run. Hedi's life changed ten years ago, when her parents were murdered by unknown assassins. She's been in hiding with her loopy aunt Lou since, as whatever they wanted she's determined they won't get it. Things change when wolves capture Lou, forcing Hedi to steal to free her -- for if she can offer up a fae amulet like her own they may trade. But it belongs to a rogue werewolf named Robson Trowbridge, who betrayed Hedi on the night of her greatest need. Over forty-eight hours, Hedi will face the weres of Creemore, discover the extent of her fae powers and possibly break her own heart in the process.
