Reality TV host Ben Harper has a problem: he owes the king of Faerie a favor. So now he has to track down the three parts of a Viking arm-ring, and return them to their place in time. This takes him through the wolf-haunted forests of Viking Age Wessex, the rowdy back streets of Shakespeare's London, and a derelict Georgian country house. Partnered with caustic, shape-changing Raven and guided by a slightly wacky goblin diary, Ben must rediscover his own gifts while facing his doubts and the queen of Faerie's minions, who will do anything to stop him.
