Wolf is on the run—from the oppressive monastery where he was raised, from the ghosts and demons that haunt the windswept moors of Devil's Edge, and from the shadows in the landscape that resemble the Devil himself.

When Wolf rescues a strange child on Devil's Edge, he takes her to a grand castle hoping to win the favor of its ruler. There he strikes up an unlikely friendship with a girl named Nest, and he thinks he's finally found a place to call home. Wolf is determined to fit in, but not everything is as it seems at the castle. Dark forces are conspiring against Wolf and Nest, and a sinister enemy is looming closer than they could ever realize.

With lies masquerading as reality, will Wolf and Nest learn who they can trust . . . before it's too late?

Critically acclaimed author Katherine Langrish has created a wonderfully spooky and richly imagined world of ghosts and magical creatures, where good may be evil and light may give way to dark.
