Caspian Vane and The Shadow Architect

Caspian Vane has a wolf-paw scar on his hand and a father who wants him dead. In the frozen heights of Vane's Reach, Caspian is being used as a living key to wake the Titan—a mountain-sized machine that carries their world.

But a darker shadow is rising. He is waking up, and he intends to delete the North forever. To save his home, Caspian must join the Shadow Pack and master the Star-Fang before the world is erased.
