Aloysius Leigh is the only living human to travel the unimaginable distance between realities, but a fantastic journey to a hidden world within his mind will leave him hopelessly lost and unable to tell what is real and what is an illusion. With only days before Mt St. Helens incinerates an unsuspecting Pacific Northwest in a gargantuan pyroclastic cloud, Leigh arrives in Daphne's San Francisco to discover he's a man with a price on his head, and everyone is looking for a payday. In order to locate Daphne and stop the eruption, Leigh must play a deadly game against a criminal organization called the Heptagon that he can't afford to lose; while in the world outside his mind, a bewildered Leigh finds himself maimed and a prisoner in a place that calls into question his sanity. Short on time and allies, Leigh must do battle in two very different worlds to keep from losing his mind...or his head. Reality is an illusion.
