Vowed in Bone, Kept in Blood

Sera Vance is an oathkeeper. She does not swear vows for people. She shows them what vows do. When the crown asks her to bind a rebel general into a peace-oath, Sera agrees, then discovers an old clause: the oathkeeper is bound alongside the sworn. Whatever kills Cassien Rook kills her first. Ten years, bone to bone, unbreakable. Cassien is patient, dangerous, and not sorry. He intends to die in the tenth year, willing, and pass the crown's leash to a successor it cannot control. Sera intends to stay alive. Between them they have a kingdom's worth of hidden clauses, a shared pulse that will not stop, and one opportunity to redraft the whole arrangement. A dark gothic fantasy romance of oaths, heresy, and two people who read the fine print on the same night.
