Rowan Calder was raised to kill wolves.

Heir to a family of hunters, she knows the laws carved into standing stones and boundary lines: wolves are the enemy. Wolves killed her ancestors. Wolves cannot be trusted.

But when she finds a young wolf trapped in one of her father's iron jaws bleeding out, dying, staring at her with eyes too human to ignore Rowan does something unforgivable.

She sets him free.

Cai is wolf-born, pack-raised, alpha's son. He should hate the human who found him. He should run the moment the trap springs open. Instead, something snaps into place behind his ribs. A thread pulling tight. A bond that doesn't ask permission.

Now the moor is waking. An ancient hunger, buried for a thousand years, is stirring beneath the peat and stone. It feeds on death. On grief. On every drop of blood spilled between wolves and humans.

And it's noticed the bond.

To survive, Rowan and Cai must return to the hollow where the first bonded pair died. They must face the thing that's been waiting. They must feed the chains that hold it-with pieces of themselves, with every moment they've shared, with a love that refuses to let go.

The cost will change them forever.

But some chains, they're learning, are worth carrying.
