In Marriage to the Sea, the Zamarins, a Jewish family of artists and activists, navigate the eco-crisis, political turmoil, personal losses, and the afterlife. In their love stories and adventures—spanning Paris, Venice, and a dreamy phantasmagorical underworld—each of them searches for the overlap between what the world needs and what they have to give. When Katya, a rebellious bi+ sustainability activist, is visited by her father’s ghost one night, she decides he’s urging her to change her life. She and her youngest sister Arielle—a recovering addict and Shakespearean actress past her ingenue sell-by date—head to Paris on a quest to help his environmentalist heroine, and, along the way, they discover unexpected new loves among the living and the dead. Their Aunt Julia (a TV villainess returned to experimental theater) also falls recklessly in love, just as her meddling brother—and the whole theater company—arrive to stay with her. At every turn, the characters are forced to navigate a world in which the sea is rising and new social movements are taking shape.
