Twig is a talented Dreamer. Sometimes she has spirit dreams--dreams that come true. But her mother has always discouraged Twig from exploring her powers for fear that they would turn her strange, like the reclusive witch-woman Cobia.

When Twig begins to have nightmares about a green light exploding from the sky and causing widespread destruction, she must find the courage to defy her mother and learn to become a Spirit Dreamer. Helping Twig on her quest are her best friend, Greyhawk, and Screech Owl, a shaman who has been banished from the village. Together, they must persuade their people to leave the land of their ancestors and journey to the mysterious Duskland, far from only home they've ever known. Can Twig convince the Elders that she is a true Spirit Dreamer--before it's too late?
