Some oaths can only be sealed in flesh. None can be broken. For nine hundred years, the Dawn Court and the Night Court have bled for a vow neither remembers making. Now the world is tearing open along its silver veins, and the only cure is a Rite: three vows, three nights, and a truce sealed by two women who should be enemies. Princess Aelindra Solvane can hear a lie in any voice. General Kerys Vhal burned a town and has never forgiven herself. Every vow must be given freely. Every touch must be chosen. And the deeper they go, the harder it is to ignore the truth hidden in the Archive, and the man who forged the war. A fae smuggler who cannot lie, a queen who is not what she seems and a wound that begs to be healed will test every promise they make. Some oaths are written in ink. The strongest are written in blood, breath and desire.
