The Natchez Trace National Parkway stretches 444 miles from Nashville to Natchez, the oldest town on the Mississippi River. It's the perfect road for a relaxed pleasure drive. Unfortunately for Luke Fereday, it's also perfect for moving drugs.

Sent to Natchez to infiltrate the organization at the center of the drug ring, Luke arrives too late to a stakeout and discovers the body of his friend, park ranger John Danvers. John's daughter Brooke is determined to investigate her father's murder but soon finds herself the target of a killer who will do anything to silence her.

Luke will have his hands full keeping her safe. But who's going to keep him safe when he realizes he's falling – hard – for the daughter of the man he failed to save?
