After stepping into a ghost circle Thorn is urged to locate the Crown of Horns, and sets off on a quest with Fone Bone to traipse through the sacred grounds of dragons, with the hope of returning with the only thing that can save everyone and everything she holds dear.

Fone Bone and his cousins are delayed in their trek home by a disastrous get-rich-quick scheme and signs of war.
