When plague strikes Bamarre, Princess Addie must fulfill an ancient prophecy.

Brave and adventurous, Princess Meryl dreams of fighting dragons and protecting the kingdom of Bamarre. Shy and fearful, Princess Addie is content to stay within the safety of the castle walls. The one thing that the sisters share is their unwavering love for each other.

The tables are turned, however, when the Gray Death leaves Meryl fatally ill. To save her sister, meek Princess Addie must find the courage to 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 the kingdom of Bamarre—hang in the balance.
