A lost friend. A forgotten relic. When the only way to save the world is to leave it.
It's senior year, and things are off to a cracking start for Lucy and the pack. Sam is gone, Tennyson is alpha, and Lucy's powers are evolving even more. Sam's mother is back and full of ideas about how Lucy should use her powers, but can she be trusted?
At least one thing hasn't changed. Lucy's dad is still evil and wants to destroy the pack. When Nikolai's shadowy cousin calls in a favor, Lucy has no choice but to travel to a parallel world to help him, and hopefully save Sam while she's there. But that world has dangers of its own, and once she's there, will she be able to return? Will she want to? And will the secret to defeating her father be hidden there all along?
