"A finely crafted ensemble and a balanced grace makes this debut novel as hard to resist as blue ribbon gumbo." --Craig Johnson, New York Times bestselling author of the Walt Longmire Mysteries, the basis for the Netflix hit drama Longmire

Dark River Rising is a tense and expertly-plotted mystery set against the bayous of Louisiana, from debut author Roger Johns.

Baton Rouge Police Detective Wallace Hartman has had better days. With her long-time partner and mentor on medical leave and a personal life in shambles, she's called to the scene of a particularly gruesome murder: the body of a known criminal has been found in a deserted warehouse, a snake sewn into his belly. Obvious signs of torture point to a cunning and cold-blooded killer who will stop at nothing to find what he's looking for.

When Federal Agent Mason Cunningham arrives on the scene, Wallace expects a hostile takeover of the case. But when a scientist with ties to the victim goes missing from a government lab, she needs Mason's federal connections as much as he needs her local insight, and the two form an uneasy partnership to solve a case that grows more complicated--and dangerous--by the minute.

Meanwhile, the killer lurks in the shadows with an agenda no one saw coming, and when Wallace and Mason threaten to get in the way they risk losing everything they hold dear. Including their lives.
