Babylon, Florida — located in the state’s panhandle — is home to the historic and winding Styx River. The very same river checkered with a dark past that the Larkin clan knows all too well. One that they would just as soon forget if they could. But the river ebbs and flows like time, siphoning the souls from the dead and marking the minds of the living. Babylon is also where the sibling pair of Jerry and Margaret Larkin live with their grandmother, Evelyn, on a blueberry farm just a stone’s throw from the river. It’s a modest living with little reward and little in the way of sustenance, which is just a paltry yield that the soil and climate are only too kind to allow. Though the farm is as much a part of their family as it is their home, even if its mortgage is drowning them in debt. But that’s just the least of their worries. When Margaret doesn’t make it home from school one rainy night, Jerry and Evelyn contact the authorities and conduct their own search to no avail. Then her corpse washes up on the banks of the river just outside their estate. She’s yet another victim of its watery grave, and yet another reminder to Jerry and Evelyn of their family turned upside down and torn apart. Ruled a homicide, Margaret’s death sparks a manhunt for the killer, who’s suspected to be one of their own. Picking up the trail gone cold may require more cunning and even more bloodshed than this close-knit community are ready to handle or even understand, for the cold moon over Babylon has other ideas.
