Lady's Knight by Amie Kaufman & Meagan Spooner

Gwen is sick of hiding—hiding the fact that she’s taken over her father’s blacksmithing duties, hiding her attraction to girls, hiding her yearning for glory as a knight.

Meanwhile, Lady Isobelle of Avington, queen bee of the castle, has never once considered hiding who she is—until now. She’s been chosen as the grand prize in the Tournament of Dragonslayers, to be given to whichever knight can claim her hand. And for the first time in her life, she can’t talk her way out of trouble.

When Isobelle discovers Gwen’s knightly ambitions, they hatch a scheme together—Gwen will joust in the tournament, disguised as Sir Gawain. Winning means freedom for Isobelle, and glory for Gwen. Losing means… well, let’s not go there.

One thing’s for sure: falling in love was never the plan.

But the best laid plans…are often trampled all over by dragons.
 
An undeniably fierce, unforgettably funny, unapologetically queer feminist romp through the England of medieval legend. Bestselling and acclaimed authors Amie Kaufman and Meagan Spooner bring readers along on an epic quest for valor, freedom, and, above all, love. A Knight’s Tale meets the Lady Jane series, with a dash of The Great!
