In a world ruled by monarchs and magic, mercy may be the deadliest act of all.

Queen Mary Tudor will stop at nothing to produce an heir—even if it means turning to the Fae.
When she strikes a secret bargain with Queen Aurora of the Light Court, ancient laws are tested. Aurora, wary of Mary’s ambition, sends her trusted advisor, Bishop Awynn, to ensure the pact is honored. But when Mary defies the agreement, the fragile peace between the Fae Courts begins to fracture.

The Dark Fae suspect betrayal. The Treaty of Bodhicitta teeters on the edge. And war looms—unless one Fae is willing to sacrifice everything to stop it.

Can one act of compassion save them all? Or will mercy spark a second war?
