Duncan Talisker has just been released from jail in Scotland. He served fifteen years for a series of violent murders he didn't commit, but knew intimately. Then, the killing begins again. On another world, a jewel is sought and a deadly god struggles to be free. Talisker and his childhood friend, Alessandro Chaplin - who is also the policeman who arrested him fifteen years previously - will undertake journeys between the worlds which mix wonder and danger in equal measure...and may result both in their deaths and the release of a deadly evil.
