One of my all-time favorites is 'The Mermaid, the Witch, and the Sea' by Maggie Tokuda-Hall. It’s this gorgeous, swashbuckling adventure with a slow-burn romance between Flora, a pirate posing as a boy, and Evelyn, a high-born girl being transported to a forced marriage. The world-building is so rich—you get magic, mermaids, and a ruthless pirate empire. The queer representation feels organic, and the stakes are high without sacrificing emotional depth.
Another gem is 'The Unbinding of Mary Reade' by Miriam McNamara, a historical fiction about real-life pirate Mary Reade. It’s gritty and lyrical, exploring gender identity and love on the high seas. If you want something darker, 'Saltfish' by Alys Arden weaves a f/f romance into a supernatural pirate tale. Honestly, these books ruined me for tamer romances—give me morally gray lesbians with cutlasses any day.
