In 1959 Cuba, Natalia San Martín was nothing short of a princess: sheltered, pampered, and courted by her very own prince, a childhood friend turned lifelong love. All that changed on the fateful New Year's Eve when Fidel Castro and his followers seized control of the country, with tragic consequences for not only the island but Natalia herself. Five years later, in 1960s New York, she's known as Natalie Martin - living a life that's bleak but thankfully anonymous.
In grief they find each other. Through loss they find love. They meet in a hospital corridor. Libby is there for Ethan, her mentor, her best friend, her husband. He's dying, and she's struggling to survive. Nick is there for Katharine, his reason for living, the love of his life, his wife. She's dying, and he holds on all the tighter as she slips away from him.
