Resilient Hearts. Thornstone Series, #3

He came back. But Thornstone is still dying. Con Mac Tíre has returned from the grey place beyond death - but the price of his freedom has fallen on the land itself. The wards are failing. The moors are coming undone. And the ancient power that once claimed him is waiting for its chance to strike again. Eleanor has one answer left: a covenant remade in blood and vows, binding herself to Con and to the wounded earth before it collapses entirely.
But healing a debt three centuries old demands more than love. It demands truth, sacrifice, and the courage to face what was broken long before either of them were born. As the ritual draws near, old allies return to stand with them, and something patient and ancient circles Thornstone - watching for the moment they'll be vulnerable enough to claim what it believes is still owed. Some debts don't end.
They only change hands. Resilient Hearts - where love becomes its own kind of law, and the land itself must decide whether it can still forgive. Book Three of the Thornstone Series.
