Description:

A huge volcano erupts, blotting out the sun and covering the land in ash — and the terrible Lord of the Locusts has been set free! In this darkest chapter yet, the Bone cousins, Thorn, Gran'ma Ben, and their brave rat-creature friend Bartleby must flee across a ruined valley toward the safety of the ancient city of Atheia. But their path is filled with "ghost circles" — strange, invisible spots where the world of the living and the dead blur together, and one wrong step could be deadly. As enemies close in, the friends will need all their courage to survive.
