Mouse, a hard-bitten, cynical woman and professional thief, finds herself in deep trouble when her attempt to rescue a seemingly helpless little girl has potentially deadly consequences in this brilliant and haunting installment of Santiago-inspired adventure. Young Penelope has long had a price on her head, and Carlos Mendoza now knows how she has outwitted her captors—and the awesome powers behind her success. As Carlos moves in for the kill, Mouse is hard-pressed to preserve her life, defend Penelope, and in so doing, save humanity. For Carlos "Iceman" Mendoza, only one thing becomes clear: in a universe of giant men, ruthless bounty hunters, and interstellar war, his greatest fear is this one girl.

Since she was a little girl, all humanity has been frightened by Penelope Bailey's awesome psychic talent and her ability to bend events—and men—to her will. Now a grown woman and living on the planet Hades, Penelope is caught in a deadly game of cat-and-mouse with a bounty hunter, a government agent, and an out-for-profit, outlaw cyborg—none of who suspect the true depths of her power.

This is the final volume of a trilogy which started with "Soothsayer" and "Oracle". In this volume, the Ice Man is beseiged by people trying to kill him, five in one month. As he sends the Gravedancer to find out who wants him dead, what he really wants to know is why the Prophet has allowed him to live.
