In the anticipated sequel to Silver on the Road, Isobel is riding circuit through the Territory as the Devil's Left Hand. But when she responds to a natural disaster, she learns the limits of her power and the growing danger of something mysterious that is threatening not just her life, but the whole Territory.

Isobel is the left hand of the old man of the Territory, the Boss-better known as the Devil. Along with her mentor, Gabriel, she is traveling circuit through Flood to represent the power of the Devil and uphold the agreement he made with the people to protect them. Here in the Territory, magic exists-sometimes wild and perilous.

But there is a growing danger in the bones of the land that is killing livestock, threatening souls, and weakening the power of magic. In the next installment of the Devil's West series, Isobel and Gabriel are in over their heads as they find what's happening and try to stop the people behind it before it unravels the Territory.
