On a stormy Gulf island where rum-driven dreams and ancient magic collide, two hard-drinking former soldiers and a half-drowned oceanographer must choose whether to burn a singing reef that spits out bones and prophecies, or let the Horned Serpent rising beneath it swallow everyone they love before the January tides reach their peak.
Oyster Island, a forgotten speck off the Louisiana coast, has always belonged more to the Gulf than to any map. Alex Pavlovic, a former Russian army officer, is just days away from firing up the resurrected Baptiste distillery when a freak storm washes a woman ashore, along with a warning written in a mirage in the sky: Beware the tides of January that carry both good and evil. You must choose, and the wrong choice leads to a horrible death. Some choices lead to worse outcomes than drowning, and on Oyster Island, the Gulf and the spirits trapped beneath it always collect their debts.
