A “richly detailed and evocative” queer retelling of the legend of Sir Lancelot, following the famous knight as he grows up orphaned, falls in love, and attempts to fulfill his destiny at the Round Table – a stunning debut novel from the author of Out East (Mary Beth Keane, New York Times bestselling author).

Hidden away on the Isle of Women, a nameless orphan has grown up among the island's sisterhood, but always at a distance. He hears whispers of a prophecy that may shed light on his destiny—and his true identity. Lancelot. Determined to master the skills and knowledge worthy of the knight he is meant to be, he begins training alongside the handsome Galehaut. As the two grow closer, they guide one another towards their truest selves. But no matter how tightly they cling to one another, each has a role to play in the wizard Merlin's grand prophecies.

When Lancelot is forced to follow Merlin to Camelot, he fights to protect his heart while seeking the fabled Holy Grail. As he grows closer to his fellow knights, Lancelot must keep an explosive secret to himself—the truth of what he left behind on the Isle of Women, of the man he truly is beneath the armor. All the while, Roman legionaries too scour far and wide for the grail. As an army encroaches on their kingdom, King Arthur and his knights must race to ensure that this powerful object doesn't fall into the wrong hands.

Steeped in rich medieval lore, THE LOST BOOK OF LANCELOT is an immersive, poignant reexamination of the most famous knight of the Round Table. It is the story of a once vulnerable boy who is forced to rise to the occasion, of a kingdom under siege, and of the battle between the old world and the new.
