An ancient evil lurks in the waters of the Concho River. After a massive storm, flood waters threaten Paint Rock, Texas, home to over three hundred supernaturals. In the water lurks a new predator, a giant, venomous snake shifter with origins in Native American myth. When one of her own is bitten, Judah Black must find a way to hunt down the monster and a cure before the venom kills her friend and more people get hurt. But nothing's ever simple. To find and catch her prey, she'll have to work with a bounty hunter named Logan Creed whose decades long hunt for the mythical snake borders on obsession. He'll sacrifice everything to complete his hunt, including her family and friends.
