"On the Wings of Dream" continues the saga of mystery and power begun in "Through the Gate of Horn." Seeking training in his new-found power of the Light of the Dance, Timothy Johnston travels through a Doorway from the earth to the distant world of Tena. There, his teachers, the once-human Dhitha, immerse him in intrigue over a dying emperor, ancient religious rivalries, an enemy race of blood-drinkers, and advanced weapons from the earth. Amid the intrigue Timothy begins to speak prophecies of destruction. Who, though, is speaking through him, and on which world will destruction fall?
