Last night, Freya's sister was bitten by a horrific beast in the snowy hills of Ysland. Now, Freya has only a few hours to find a cure for this strange plague before her sister becomes a ravening fox demon. With her husband Erik and the young witch Wren at her side, Freya discovers that the blood-thirsty monsters have already ravaged her homeland as she explores deserted cities full of ghosts and meets a few lonely survivors on the edge of madness. She finally seeks answers in the ancient city of Rekavik where she must face the deadly witch queen Skadi and the vicious warrior Leif Blackmane. But the only person who can cure the demon plague is the same person who created it, a stranger from a distant land who carried a sword full of captured souls, a man who was murdered five years ago... But not even death will stop Freya from saving the people she loves.
