Wren Calloway is thirteen, and every morning at 5:34 a.m. she rows her father's johnboat out over the deep spot at Millbrook Reservoir. Her father drowned there two years ago. The divers found his boot at a hundred and twenty feet. Then a black horse stands in the shallows at dawn, fetlock-deep in water that doesn't ripple around its hooves. And a new boy arrives at the marina with damp hair, expensive boots he hasn't had time to scuff, and a patience no teenager should have. They are not two things. Travis Okafor, the sheriff's recovery diver, has pulled eleven bodies from this reservoir in twelve years and keeps a private logbook of the rules. A woman with cold hands steps off the Citgo bus and tells Wren what the old country called the creature that wears two shapes and what it takes in exchange for the thing the drowned were not given back. The Each-Uisge . The Scottish water-horse. The wanting is the bond. The iron is the weapon. The water only takes. A Book in the Seer Fairies series. Each book is a standalone small-town horror novel; read in any order.
