Merlin's world of Avalon faces destruction, and Merlin himself has disappeared. Only one possible savior remains - Basil, the once-tiny lizard who has become the greatest dragon of all time. But even as he enters into battle, Basil knows his struggles have only begun. He must find the source of this chaos - a dark being hidden deep in the Haunted Marsh - before it finally gains ultimate power. To triumph, Basil must risk losing everything.
