Starling days by Rowan Hisayo Buchanan

Mina is staring over the edge of the George Washington Bridge when a patrol car drives up. She tries to convince the officers she's not about to jump but they don't believe her. Her husband, Oscar, is called to pick her up. Oscar hopes that leaving New York for a few months will give Mina the space to heal. They travel to London, to an apartment wall-papered with indigo-eyed birds, to Oscar's oldest friends, to a canal and blooming flower market. Mina, a classicist, searches for solutions to her failing mental health using mythological women. But she finds a beam of light in a living woman.
