Eight Rivers of Shadow

Luke Manchett is doing his best to blend in to the background of high school, despite the Host of eight hostile spirits he inherited from his dead father. He's made a deal with the devil to banish them, and is trying to ignore the haunting dreams spawned by his father's Book of Eight. The one good thing to come from the whole mess: his girlfriend, Elza. And then Ash, a strange new girl with stark white hair, requests his help-- and his Book of Eight-- to save her twin sister, who was attacked by a demon.
