Antonio Marez is six years old when the woman who helped usher him into the world comes to stay with his family in New Mexico. Venerated by some as a miracle-worker—and disparaged by others as a bruja—Ultima, a curandera, or healer, opens Tony’s eyes to the spiritual roots of his culture, and introduces him to a magical, if sometimes frightening, new world: a realm in which she operates as a shaman. As Ultima shows Tony how to cure ailments, reverse curses, and restore peace to those who have lost it, he embarks on a singular quest, one in which he probes the family ties that bind and rend him, questions the Catholicism that shaped him, and explores the Spanish, Mexican, and Native American influences that informed not only his heritage, but his very sense of self. And at each life turn there is Ultima, who was there the day he was born . . . and will nurture the birth of his soul.
