The battle for Imperia

"Team Dragon is facing their most challenging adventure yet! Luca, Yazmine, and Zane have been dropped in the ancient dragon city of Dracopolis. They have only one more Thunder Egg to return before the prophecy can come true, and dragons can return to Imperia. The people of Dracopolis are counting on Team Dragon to win, but the evil ruler Dartsmith never plays fair. Luca, Yazmine, and Zane will need all the help they can get if they're going to defeat him for good and finally bring peace to Imperia"--Provided by publisher.
