Cursed by the Key of Forgetting, Seth has lost all memory of his past—his relationships, his experiences, and who he really is. All he knows is that his new mentor, the dark unicorn Ronodin, is leading him on a dangerous journey to the Phantom Isle, a secret gateway to the Under Realm.
Kendra is frantic to find her missing brother, but the quest will take her and her companions far from Wyrmroost to Crescent Lagoon. If Kendra and her friends can help its caretaker reclaim control of the fallen dragon sanctuary, they might uncover the answers they need to rescue Seth.
Meanwhile, with each sanctuary the dragons overthrow, the Dragon King comes closer to the dawn of a new Age of Dragons. With the forces of darkness on the march, can the Dragonwatch gather enough power to win the epic dragon war?
