Diana O’Toole is perfectly on track. She will be married by thirty, done having kids by thirty-five, and move out to the New York City suburbs, all while climbing the professional ladder in the art auction world. She knows her boyfriend, Finn, a surgical resident, is about to propose on their getaway to the Galápagos. But then a virus that felt worlds away appears in the city, and on the eve of their departure, Finn breaks the news: it’s all hands on deck at work. In the Galápagos, Diana finds herself examining her relationships, her choices, and herself.
