This one's personal

Natchez Trace Ranger and historian Emma Winters hoped never to see Sam Ryker again after she broke off her engagement to him. But when shots are fired at her at a historical landmark just off the Natchez Trace, she's forced to work alongside Sam as the Natchez Trace law enforcement district ranger in the ensuing investigation.

To complicate matters, Emma has acquired a delusional secret admirer who is determined to have her as his own. Sam is merely an obstruction, one which must be removed. Sam knows that he has failed Emma in the past, and he doesn't intend to let her down again. Especially now that her life is on the line.
