With only three nights until the full moon, Claire reluctantly follows Ronan Vale, the powerful Alpha of Nightvale, into a hidden world ruled by ancient laws and dangerous secrets.
But Ivy is no ordinary child. Her rare White Moon heritage makes her the center of a growing conflict between powerful wolf packs and the mysterious Wolf Covenant. As long-buried secrets about Claire's husband begin to surface, she realizes that everyone wants something from her daughter.
Now, with powerful Alphas challenging her authority as a mother, Claire must confront an entire supernatural world to protect the one person she loves most.
They came for her daughter. They never expected a human mother to stand against them all.
