Marielle Jones has been hired to drive eight-year old Tyler, his
ten-year old sister Mickey, and their maternal grandmother on a camping
trip across Oregon. When Tyler claims someone pushed him into a river,
she doubts it. But when their party is shot at in a lava cave and
Tyler's horse is spooked while he's riding on the Oregon dunes,
Marielle begins to wonder: What's going on here? Who wants Tyler dead?
Add the mystery of the kids' missing mother, the suspicious actions of
their grandmother, and the puzzling attention of a fellow camper, and
Marielle is thrown into amateur sleuth mode. And where does a lazy,
mixed-breed hound, an elegant purebred one, and a suave college
instructor fit into the picture? It all comes together in the musty,
dark corridors of an historic old military fort.
