Sarah loves living in the pristine Toutle Valley with her parents, her
sister Kathy, and her horse, Cimmaron. They’re all used to occasional
tremors from nearby Mount St. Helens. But when the volcano erupts,
Sarah’s family is forced to evacuate, leaving behind their house, their
chickens, their cows and Cimmaron.

As Sarah hears the news of hot
ash and mud flows covering her valley, she wonders why God would let
such a terrible thing happen. Since He doesn’t seem to be answering her
prayers, Sarah decides to solve the problem herself. Somehow she will
get back into Toutle Valley to save Cimmaron.
