Mark Roberts is a nervous, anxious office worker living a mundane existence in New York City. But when he becomes beset by recurrent nightmares and hallucinations of magical rituals, he tries to learn what is happening to his once-normal life. His search for answers takes him from his home in Manhattan to the long-time family home in Massachusetts, before he learns that his fate is intertwined with a ruined tower in the highlands of Scotland. Along the way, he discovers his own recently developed aptitude for magic is tied directly to a cycle of reincarnation that puts him in the center of a centuries old battle for possession of his restless soul. As he is initiated into the secret world of magic and sorcery, Mark discovers that there is no such thing as simple coincidence and that hidden hands pull at the strings of his life.
