As an Omega, 17-year-old Sarah is used to being at the bottom of the pecking order, even in her new pack and new high school. But her usually-boring life changes when she turns 18. She expects to shift—and nothing happens. Now, as if being an Omega isn’t bad enough, Sarah is also human. But Sarah, to her surprise, soon finds her mate: in the pack’s handsome and compassionate Alpha. And the lowly Omega finds herself rocketing to the top of her pack’s status as the new Luna. Just as it seems that life is finally going her way, Sarah learns of a terrible betrayal that results in tragic death, exile, and upheaval of what should have been her storybook ending… Or does it?
