He bound her shadow to his will. She stole his heart anyway.
Nyra Vale is a shadow-binder and a master thief, surviving the deadly, frost-bitten alleys of Varyn by trusting no one and keeping to the dark. She spins night into blades and flawless escapes, answering only to herself. But when a high-stakes heist in the royal archives goes catastrophically wrong, Nyra finds herself caged by consecrated light and completely at the mercy of the city’s most feared man.
Cassian Rook is the Crown’s ruthless Spymaster. A man composed of cold arithmetic, deadly precision, and secrets, he doesn’t want her life—he wants her magic. Faced with execution, Nyra is forced into a blood-ink geas, an ancient magical vow binding her shadow strictly to Cassian’s command. She becomes his weapon, his operative, and his most dangerous asset in a covert war against a fanatical religious cult plotting to overthrow the dying Queen.
She is his captive. His tool. His perfect assassin. She also absolutely loathes him.
But as they navigate treacherous noble courts, deadly cathedral catacombs, and a labyrinth of political betrayal, the rigid boundaries of their vow begin to blur. Beneath Cassian’s brutal discipline and ice-cold exterior lies a man fiercely protective of his city—and increasingly, dangerously protective of her. The magical tether forces her tactical obedience, but the simmering, undeniable heat between the sarcastic thief and the brooding spymaster obeys no rules.
With Throne Day approaching and the city on the brink of holy war, Nyra and Cassian must trust each other to pull off the greatest magical heist in the realm’s history. If they survive, he has promised to set her free. But walking away from the man who holds her tether might be the one lock she doesn’t want to pick.
Welcome to a world of dark magic, lethal politics, and a romance that burns brighter than consecrated light. Perfect for fans of Sarah J. Maas, Leigh Bardugo, and Danielle L. Jensen, The Shadow Binder’s Vow is a gripping dark fantasy romance that will leave you breathless.
