In a Raven's Shadow (Hardcover) (ISBN-13: 9780228849223)

Torment is a terrible thing; it festers and consumes and is nurtured by each ugly experience. The teacher is a product of his past-left embittered by events best forgotten. He is a loner, avoiding any social contact that might inflict pain or distress. His classroom is his refuge, an island of solace, a place where he can embrace the innocence and kindness missing in the outside world. When one of his favorite students suffers a gruesome death, he reaches a breaking point. But will a new dark path destroy him?

'The raven gave a loud caw, flapped his wings and took to the air..... this was an invocation impossible to ignore.'
