Blood in the Bayou by C. M. Sutter

FBI agent Jade Monroe heads to Louisiana where human bones have been found deep in bayou country, and the locals aren’t too excited about the FBI poking around. A helpful hunter offers to break through that barrier for Jade, but a bone-chilling blindside ensues. A dangerous cat and mouse chase through the swamp is just the beginning, yet the question remains—is Jade the hunter or the hunted?
