The Battle for Rondo — Emily Rodda

Peril awaits Leo and Mimi on their return to the fantastic world of Rondo. With the help of Rondo's seven best witches and wizards, their friends have made plans to combat attacks of the Blue Queen. But it soon becomes clear that defence is no longer enough. The queen has a dragon on her side, and is plotting a terrible revenge on all those who have defied her. A daring plan, a reckless quest and a mysterious prophecy test the friends' wits and courage to the limit as they plunge into an adventure packed with suspense, shocks and danger and ending at last in the battle that will decide Rondo's future forever.
