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 . . .

Trapped on a ledge, there's no way of reaching him - until Kirstie remembers some disused silver mine workings. Could an old site plan help her to carry out a daring rescue?
