The Oathbreaker's Coart

Wren has spent her whole life as a tool of the Magpie's guild — an orphan trained in the Warrens beneath Duskhaven to lie, steal, and slip through rooms she was never meant to enter. Now the guild has planted her in the royal court under a stolen name, Lady Wren Ashford of a conveniently extinct border house, with one impossible task: steal the Sovereign Oath, the binding-relic that ties all of Ilvaren's magic to the crown. The old king is dying, the Oath is fraying, and whoever holds it when he dies inherits the realm's power.

She is caught on her first night — not by guards, but by Cassian Varel, the King's Whisper, the court's spymaster and the King's disowned nephew. He should hang her. Instead he collars her with a bargain: play the role of his informant, or the noose. Forced to work beside the one man she cannot fool, Wren discovers the succession war is a smokescreen. Her own guild does not mean to seize the Sovereign Oath. They mean to break it — to shatter the binding and let magic run wild and ownerless through Ilvaren, whatever it costs. And the price of breaking the oldest oath in the world will be paid in blood: the Reckoning, magnified across a whole kingdom.
