In an isolated stretch of eastern Kentucky, on a hilltop known as Blade Ridge, stands a lighthouse that illuminates nothing but the surrounding woods. One day its builder is found dead at the top of the light, and his belongings reveal a troubling local history.

For deputy sheriff Kevin Kimble, the lighthouse-keeper’s death is disturbing and personal. Years ago, Kimble was shot while on duty. Somehow the death suggests a connection between the lighthouse and the most terrifying moment of his life.

Audrey Clark is in the midst of moving her large-cat sanctuary onto land adjacent to the lighthouse. Sixty-seven tigers, lions, leopards, and one legendary black panther are about to have a new home there. Her husband, the sanctuary’s founder, died scouting the new property, and Audrey is determined to see his vision through.
