Luna was destined to be alpha once he became an adult, but before he got the chance, his own brother, Rajor, framed him for a crime no one committed, leading to Luna being banished from the pack. Declared a lone wolf, never to know the company of another wolf, Luna turns bitter as he learns to accept his new fate. Yet even as he does, other wolves, strange two-legged creatures, and one mockingbird, force themselves into his life, driving him through a gauntlet of trials where he must reconnect with the alpha he was born to be, or turn away from it forever - assuming he survives.
