This richly imagined novel invents a backstory for the famous Nativity tale of the three wise men—Melchior, Balthazaar and Gaspar—who follow a star in search of the prophesied king. Fletcher (Shadow Spinner
) centers the story on Mitra, a Persian teenager, and her young brother, the fragile, kindhearted Babak. The pair was forced to flee after their father's unsuccessful coup attempt against the reigning monarch, Phraates. Mitra successfully disguises herself as a boy and a beggar—until Babak unwittingly reveals his ability to foretell the future through his dreams. His prophetic visions attract unwanted attention, most perilously from Melchior, an out-of-favor Magus who kidnaps the boy so Babak can dream exclusively for him, despite obvious risks to the boy's health. (He grows weaker with every dream.) There's a bit too much going on—two romances for Mitra, multiple escapes and recaptures, squabbling Magi—and the pace occasionally advances as languidly as a camel journey from Persia to Bethlehem. But Mitra is feisty and honorable, and Fletcher, with lush and often poetic language, somehow ties her many strands together, drawing a subtle parallel between the humble circumstances of the unnamed baby's birth and the empathetic suffering of Babak, a prince in exile. Ages 12-up. (Sept.)
