The Bone cousins, Thorn, and Gran'ma Ben are all there to defend the Valley and stop the return of the Lord of the Locusts. When Thorn goes inside a ghost circle, she hears a voice urging her to seek the Crown of Horns. What follows is another dangerous journey for Thorn and loyal Fone Bone as they race to the sacred grounds of the dragons, searching for...

The war in the valley rages on while the Bones, Gran'ma Ben, and their loyal rat creature cub venture on a dangerous trek to Atheia, the old city of the royal family. The goal is to bring Thorn to safety, but to do so they must first travel through fields of the mysterious ghost circles where reality meets the supernatural -- and all this while fending off deadly attacks from Briar, Kingdok, and the rat creatures.

A prequel to the Bone saga tells of young Princess Rose's quest to defend the small towns of the Northern Valley from dragon attacks and the impact that her actions had on the lives of both friends and foes in the years ahead.
