Caroline Ryder doesn't believe in fate. She doesn't believe in destiny either. If either existed than her mate wouldn't have been killed before she had the chance to know him. Alone and bitter, Caroline pushes everyone away to keep her heart safe until a lonesome Alpha asks her for help. Trip fought for his species in the Feral War but failed to protect the only thing that mattered to him, his mate. Returning to his home alone, Trip intends to dedicate himself to leading the pack, only he can't do it alone. Intrigued by Caroline, a lone wolf with a wall built firmly around her, he decides to offer her what any girl would kill for; the chance to be Luna.
