Bound by honor. Tempted by love.

Sir Tristan of Arundel has sworn an unbreakable oath—to protect his lord's daughter and uphold his knightly duty at all costs. Fierce in battle and loyal to a fault, he never wavers in his duty. But when he meets Lady Eleanor, the spirited and kind-hearted noblewoman he is sworn to guard, his heart is tested in ways he never imagined.

Lady Eleanor has always known her fate lies in a strategic marriage, yet she longs for a love that burns brighter than duty. As war looms and treachery threatens, she finds herself drawn to the one man she can never have—the knight sworn to protect her, not love her.

Torn between loyalty and forbidden desire, Tristan and Eleanor must choose: honor their vows or surrender to a love that could cost them everything.

Will they defy the chains of duty, or will their love be lost to the demands of war and honor?

Perfect for fans of epic medieval romance, The Knight's Oath is a sweeping tale of love, sacrifice, and the power of an oath that could change everything.
