After finally realizing her dream of becoming a Seeker, Bryn is ready for her first official challenge. And she can't wait to face it with her good friend and fellow new Seeker Ari by her side. When an ancient threat to the Realm emerges—a plague that threatens to destroy everything that she and the rest of the Council have sworn to protect—Bryn swears she will find a cure. But when Bryn tries to voice her ideas on how to best handle things, the other Seekers seem to turn against her—including Ari. As the plague jeopardizes the Realm, Bryn realizes she must put the fate of the Realm in her own hands, taking huge risks in the process. And when those risks endanger her and Lilja, Ari's beloved dragon, Bryn must face some tough choices. Can Bryn figure out how to rescue herself, her friends, and the entire Realm from an unimaginable fate?
