Burn out - Marcia Muller

Traumatised by the events that took place in The Ever-Running Man, Sharon McCone decides to take an extended holiday at her ranch in California's high desert country. Though she plans to contemplate her future, McCone soon becomes distracted by a troubled yet highly secretive Native American woman.

When traces of violence at an abandoned resort lead directly back to the mysterious woman, the county sheriff's deputy handling the case asks McCone for assistance.
The investigation leads McCone across the state and back to her own ranch where imminent danger lies closer than she ever expected and where her future and her life itself may hang in the balance.
