A wild and dangerous mountain setting and a daughter who lives, breathes and sleeps horses is a recipe for trouble for ranch owner, Sandy Scott. But Kirstie is undaunted by her mother's warnings. She's at her happiest riding the trails through the tall forests and deep canyons of the Meltwater Range . . .

Ahead lies danger - sub-zero night temperatures, coyotes and mountain lions, and of course the ever present threat of another disastrous flood . . .
