Mercy Thompson returns in another thrilling instalment of the major urban fantasy series from No. 1 New York Times bestselling author Patricia Briggs

'Patricia Briggs never fails to deliver an exciting, magic and fable filled suspense story' Erin Watt, No. 1 New York Times bestselling author of The Royals series.

Mercy Thompson, car mechanic and shapeshifter, must stop a disaster of world-shattering proportions in this exhilarating entry in the No. 1 New York Times bestselling series.

In the supernatural realms, there are creatures who belong to winter. I am not one of them. But like the coyote I can become at will, I am adaptable.

My name is Mercy Thompson Hauptman, and my mate, Adam, is the werewolf who leads the Columbia Basin Pack, the pack charged with keeping the people who live and work in the Tri-Cities of Washington State safe. It's a hard job, and it doesn't leave much room for side quests. Which is why when I needed to travel to Montana to help my brother, I intended to go by myself..

But I'm not alone anymore.

Together, Adam and I find ourselves trapped with strangers in a lodge in the heart of the wilderness, in the teeth of a storm of legendary power, only to discover my brother's issues are a tiny part of a problem much bigger than we could have imagined. Arcane and ancient magics are at work that could, unless we are very careful, bring about the end of the world . . .
