"Step follows step. Hope follows courage. Set your face toward danger. Set your heart on victory." Princess Meryl dreams of one day protecting the kingdom of Bamarre, while timid Princess Addie is content to stay always within the safety of the castle walls. The one trait they share is their devotion to each other. Their world is turned upside down, though, when Meryl is stricken by the incurable Gray Death. To save her sister, Addie must set out on a dangerous quest filled with dragons, unknown magic, and death itself. Time is running out, and the sisters' lives -- and the future of Bamarre -- hang in the balance.
