When college hockey players, Ellis O'Rourke and his best friend Hunter crash their car deep in the Appalachian Mountains, survival is all that matters, until they find a glowing staircase circled by mushrooms and step into a realm that no one believed existed. They've crossed on the one night mortals are never meant to wander, the night of the Wild Hunt. With magic thick in the air and monstrous riders on the prowl, the boys are marked as prey. But just before the Hunt can claim them, a fae princess intervenes. Asteria, shouldn't care about mortals. Yet something about Ellis makes her reckless, so she strikes a dangerous bargain with the Hunt's master, Gwynn ap Nudd. Now Ellis and Hunter are trapped in a world they only know about from stories. Asteria must decide how far she's willing to go to protect these humans.
