Nathan Ward is whisked away as a child to live in the forested land of Thornyhill under the guidance of a man named Bartlemy. As he grows up, Nathan senses he is being watched from the surrounding Darkwood, and his visions start to come true. A jeweled, green stone cup from his visions resembles one lost by the Thorn family hundreds of years earlier. When Nathan learns the cup is from another world, he and his friend Hazel travel into dreams, lands, and legends that hold the answers.
