Darkest Journey (Krewe of Hunters, #20)

They say it's about the journey, not the destination…

Charlene "Charlie" Moreau is back in St. Francisville, Louisiana, to work on a movie. One night, she stumbles across the body of a Civil War reenactor, the second murdered in two days. Charlie is shocked to learn that her father—a guide on the Journey, a historic paddle wheeler that's sponsoring the reenactment—is a suspect. 

Meanwhile, Ethan Delaney, new to the FBI's Krewe of Hunters, is brought in on the case. He and Charlie have a history of their own, dating back to when he rescued her from a graveyard—led there by a Confederate ghost! 

Charlie arranges a Mississippi River cruise so she and Ethan can get close to the reenactors, find out who knows what, who has a motive. They discover a lot more as they resume the relationship that ended ten years ago…but might die, along with them, on the Journey.
