Tom and Rosey, a childless, little couple, have given up hope of being parents. Then they meet Duggan, a strange, quiet, unearthly child who would change their lives. They know immediately that there is something different about their new foster son; once they determine that he is truly not of their world, an adventure begins. Duggan's powers grow as his young body does, and his parents watch in wonder as he learns of his alien powers and abilities. He can read minds, and he knows if the family is being observed. He can take them for fantastic journeys in his invisible spaceship, soaring fearlessly through the clouds and through the terrifying depths of the seas with equal ease. Together, they explore his unknown potential and power, safe from prying eyes on their rural homestead. But the one thing that Duggan works hard to conceal from his human parents is the depth of his love for his adopted world and his family. Earth's gentle rhythms and savage beauty engages his imagination in ways that his snow-covered home world never could. Given a choice, Duggan would stay on Earth forever. To him, Earth is a giant playground, a place where his prodigious imagination can take flight without fear. But somewhere, in the back of his mind, Duggan knows fear, as did Tom and Rosey. They all fear the inevitable-that one day, Duggan's people will return for him.
