Ingrid has Valkyrie blood—she can see the dead. After a year with her perfect boyfriend Fenrir, she's finally meeting his family in the remote Norwegian wilderness. But as their car winds deeper into the forest, murdered women's spirits begin to appear with desperate warnings: he's leading her to a werewolf clan that traffics women. When Ingrid flees into the darkness, she discovers the forest holds countless ghosts of women who came before her. Some want to help her escape. Others are part of an elaborate trap. With the clan hunting her through frozen streams and hidden cellars, Ingrid must decide which spirits to trust—and whether she can survive long enough to expose the horrors buried in these woods. Because she's not the first woman Fenrir has brought here. Just the latest.
