Rip Tide (Gideon Thorn Book 9) by Michael Newton

​Gideon Thorn returns in a deadly hunt along the Mississippi. 

When a paddle steamer is torn apart by an unseen force on the Mississippi River—leaving only one survivor—newspaper reports of the massacre stir Gideon Thorn into action. Drawn to Natchez by the scent of blood and mystery, Thorn faces his most elusive quarry yet: an aquatic predator capable of destroying ships and devouring crews without a trace.

But the monster in the water isn’t the only threat lurking in Mississippi.

Navigating the treacherous racial politics of the post-Reconstruction South, Thorn uncovers a town rotting from within. Freedmen fight for dignity in a white supremacist stronghold still bitter over losing the Civil War. As Thorn digs deeper, confronting both ancient terror and modern hatred, he finds himself walking a razor’s edge between predator and prey, justice and vengeance.

Rip Tide is a pulse-pounding fusion of Southern Gothic horror and supernatural frontier adventure…where even the river runs red.
