Set in the French Riviera in the late 1920s, Tender Is the Night is a novel by F. Scott Fitzgerald about the tragic romance of Dick and Nicole Diver and young actress Rosemary Hoyt. Dick is a brilliant young psychiatrist who marries his mentally ill patient, Nicole, who also happens to be an heiress. The novel explores themes of social class, mental illness, sexual abuse, and codependent love and is considered one of the best books of the 20th century. Tender Is the Night was Fitzgerald’s fourth and final novel, and was based almost entirely on his relationship with Zelda.
