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 cutthroat art auction world. She's not engaged just yet, but she knows her boyfriend, Finn, a surgical resident, is about to propose on their romantic getaway to the Galápagos—days before her thirtieth birthday. Right on time.
