Tanis - his Emerald Dragon, Demios - and the Dragon Riders have defeated the Demons of the Dark Lord for now. But Mt. Drago is still in danger without the remaining two crystal keys. Now the inhabitants of the mountain have a new threat. One of the Aguiva dragons has escaped, and could jeopardize the harmony of their existence if discovered by the human world outside.
Meanwhile, Tanis manages to impress with Bubo, an Aguiva Dragon that gives him more than he ever dreamed of, or at times can handle. In the heart of Australia’s outback, a new home at Mt. Arcadia is being established by The Ariella, Queen of the Dragons. It will house her new Dragons, the Amphiteres.
Times are uncertain as Tanis and the Dragon Riders brave the dangers of a newly established home, discover new worlds that could change the course of their lives, and end the terrible battle that looms closer every day.
