Because an oracle tells her that he must not die, Tellurith, the Head of a great ruling House, retrieves a battered outlander left for dead in the streets of the legendary city of Amberlight. Although stripped of his memory the man may know of a threat to Amberlight's unique possession: the motherlodes of the qherrique; the pearl-rock that gives the Riverworld rulers their most powerful tool. Tangled in intrigue, insurrection and brutal warfare, it takes a cataclysmic upheaval for Tellurith and the stranger to begin to understand the more-than-human mystery that first brought them together.
