Kira de la Fuente's vacation to the land of her ancestors turns into a nightmare when her guide abandons her in the mountains of Peru. Without provisions or shelter, she is relieved when the enigmatic Amaru comes to her rescue. A powerful, self-assured man in his prime, he possesses an uncanny knowledge of ancient Incan ways. And for good reason.

Ever since he crossed the sun god centuries ago, Amaru has been paying the price—a life of isolation and misery, prayer and atonement. Kira's arrival brings many good omens and Amaru comes to believe she might be the one to finally free him from his unearthly prison. But one last test has yet to be revealed, and it is Kira, not Amaru, who must pass it.
