Known as the illustrator of Paton Walsh's Birdy and the Ghosties, Marks pens his own easy-to-read fantasy, a rather muddled tale of an honest man disgraced and discharged from his court post when he is suspected of theft. Years later, with the aid of a noble and mysterious woman who appears and disappears without warning, his daughter Magpie finds the golden key to a box the Queen had given her father as a token of trust. Inside are deeds to enough land to lift her family from poverty—a satisfying enough end to a tale of honesty rewarded, though the plot's logic won't bear much scrutiny. The ink-and-watercolor illustrations look suitably long- ago-and-far-away, with Magpie as a perpetually windblown waif. (Fiction. 6-9)
