The isolated, sleepy little village of Timber Falls--built on the bend of a swift mountain river--swells during the summer months as tourists flock to town to run the river, lured there by the Class IV and Class V rapids.

A gruesome murder of a college student--a river rat--brings the FBI to town.

Haley Martin used to be one of those river rats during her college years. Now she owns the Timber Falls Bar and Grill, drawn back to the picturesque village seven years ago after the tragic death of her wife.

Lynn Carter, a disgraced LAPD detective, was offered an out--a position on a team of unorthodox FBI agents. After a month of training, she was sent out on her own without a team or a partner. Her commander, nothing more than a mysterious voice on the phone, dished out assignments.

When he sent her to Timber Falls--a town by only the stretch of the imagination--she had no idea she would find her peace there. No idea she might find love.

But a serial killer preying on the tourists that the town relies on for survival takes precedence as clues lead her to an unlikely suspect.
