Inti Flynn arrives in the Scottish Highlands with fourteen grey wolves, a traumatised sister and fierce tenacity.
As a biologist, she knows the animals are the best hope for rewilding the ruined landscape and she cares little for local opposition. As a sister, she hopes the remote project will offer her twin, Aggie, a chance to heal after the horrific events that drove them both out of Alaska.
But violence dogs their footsteps and one night Inti stumbles over the body of a farmer. Unable to accept that her wolves could be responsible, she makes a reckless decision to protect them. But if the wolves didn't make the kill, then who did? And can she trust the man she is beginning to love when he becomes the main suspect?
