Maggie Millner's seductive debut is a novel-in-verse about a woman in her late twenties who leaves a long-term relationship with a boyfriend for another woman. The affair thrusts her from an outwardly conventional life into queerness, polyamory, kink, and unalloyed, consuming desire. What ensues is an exploration of obsession, gender, identity-making, sexual experiment, and the art and act of literary transformation. Couplets is a dazzling fusion of form and content, chronicling the strictures, structures and pitfalls of relationships - the mirroring, the pleasing, the small jealousies and disappointments. Playful, clever, lovestruck, griefstruck, its narrator dances a tightrope of her own invention with captivating passion and skill.
