New Orleans musician Birch "Buzz" MacKinlay used to think she was the only werewolf in the world. But that was before the mysterious and captivating Rowan welcomed her into his pack, and showed her that shapeshifters- all kinds of shapeshifters- were hiding in plain sight everywhere. Now Birch is on a crash course by day to learn everything she can about the secret "shifter" world, while gigging as a bass player at night. But there's a problem with this dream come true: a dark and growing danger threatens the shifters, who are beginning to mysteriously disappear or die. Faced with hecklers, drunks, stalkers, and incompetent bandmates in one life and fang-toothed double agents in the other, Birch doesn't know who to trust- especially now that she's the target of a powerful enemy. With menace closing in fast, Birch must find a way to save her new pack... or lose everything that matters, including her own life.
