Magic has returned to the world, but so has an ancient foe.
Erin Donnelly, descendant of Cu Chulainn and Champion of the Folk, searches for Nechtan—her lover cursed to live as a stag for a year and a day. Enlisting the aid of allies, Erin maintains a vigil, turning back hunters and predators who might harm Nechtan in the wilds of the magical otherworld.
But when Stangr Iron-skinned escapes his imprisonment in the River of Time, he has one thing on his mind—revenge on Nechtan. Stangr’s thirst for vengeance takes him from the Seelie courts of the otherworld to the windswept Great Plains.
Can Erin find Nechtan before Stangr tracks him down? Erin beat Giwargix the Dragon-Slayer, but can she defeat a jotunn-blooded Viking impervious to blades and bullets?
