When his father dies, Devon is sent to live at a mansion called Ravenscliff, perched atop Devil's Rock on the craggy coast of New England. Here, Devon suspects he will find the truth of his past. Indeed, Devon discovers he is a Sorcerer of the Order of the Nightwing and that his heritage is proud and noble. But he learns something else, too: there exists at Ravensliff a Hellhole, and the demons are scratching to get out...
