The union of the five realms stands on the brink of destruction. All hope lies with the secret heirs of Toran, but no one knows who they are, not even the heirs themselves. Reann, a 17-year-old keeper of the library in Toran's former castle, must find the next heir or leave the castle when she turns 18. With the help of Verick, a handsome young nobleman, Reann seeks to solve the mystery of the five rumored heirs. Meanwhile in the east, champion dragon rider Terith, one of secret heirs, fights to defend the kingdom from an invasion. But first he must ride against the black-hearted Pert in a cross-country dragon race that will determine the fate of the kingdom and Terith's love Lilleth. Reann and Terith's quests will put both their lives in jeopardy. One rider will fall. One fate will rise.
