Like everyone else in the settlement of Mistaken, Greer Mackenzie is trapped. Founded by an ambitious lumber merchant, the village is blessed with rich natural resources that have made its people prosperous--but at a cost. The same woods that have lined the townsfolks' pockets harbor dangerous beasts: wolves, bears, and the Bright-Eyeds--monsters beyond description who have rained utter destruction down on nearby settlements. But Mistaken's founders made a deal with the mysterious Benevolence: the Warding Stones that surround the town will keep the Bright-Eyeds out--and the town's citizens in. Anyone who spends a night within Mistaken's borders belongs to it forever. Greer, a mapmaker and eccentric dreamer, has always ached to explore the world outside, even though she knows she and her longtime love, Ellis Beaufort, will never see it. Until, on the day she and Ellis are meant to finally begin their lives together, Greer watches in horror as her beloved disappears beyond the Warding Stones, pursued by a monstrous creature. Determined to rescue Ellis, she figures out a way to defy Mistaken's curse and begins a trek through the cold and pitiless wilderness. But there, Greer is hunted, not only by the ruthless Bright-Eyeds but by the secret truths behind Mistaken's founding and her own origins.
