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 an associate specialist at Sotheby's now, but her boss has hinted at a promotion if she can close a deal with a high-profile client. 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 Galapagos days before her thirtieth birthday. Right on time. But then a virus that felt worlds away has appeared in the city and on the eve of their departure, Finn breaks the news: It's all hands on deck at the hospital. He has to stay behind. You should still go, he assures her, since it would be a shame for all of their nonrefundable trip to go to waste. And so, reluctantly, she goes. In the Galapagos Islands, where Darwin's theory of evolution by natural selection was formed, Diana finds herself examining her relationships, her choices and herself and wondering if when she goes home, she too will have evolved into someone completely different.
