The search for King Arthur’s Excalibur invites danger…and potentially love in this sapphic historical romance, perfect for fans of Cat Sebastian and Freya Marske. Lady Edith Darling is supposed to live a quiet life in her family’s manor. She is not supposed to go unchaperoned on a quest to find Excalibur. But Edith won’t let that stand in her way, especially not when she’s on this mission to honor her beloved grandmother’s dying wish. Determined to prove her grandmother right, Edith packs her satchel with Arthurian legends, pastries, and her grandmother’s ashes, and runs off to hire a mercenary. Thomasin Shaw leads the most feared gang in London. For years, she had the constabulary safely in her pocket, until a scandal involving the chief inspector’s wife was brought to light. Now he’s demanding an enormous sum of money–without which Thomasin will lose the protection of the police along with her criminal empire. But when the rich Lady Edith waltzes into her life seeking an escort for a treasure hunt, Thomasin sees a willing kidnapping victim and a massive ransom. As Edith’s clues lead them to underground chambers booby-trapped with arrows, doors locked with arcane puzzles, and even Arthur’s fabled round table, Thomasin finds herself swept up in the quest, and in Edith herself. Edith is also drawn to Thomasin, despite the ruthless mask she wears. But the chief inspector won’t let Thomasin forget her crimes, and Edith’s father is intent on bringing her home. Every legendary quest has an ending, but finding Excalibur might not be enough to make this a happy one.
