The novel succeeds, however, at transporting readers through the rollercoaster of highs and lows that defined the glittering world of 1920s Paris and the superb writers who lived there at that time. McLain’s historical account of Hemingway’s grandiosity, flight of ideas, rapid mood swings, and passions seems credible. Intrigued readers might hypothesize that he suffered from bipolar disorder, posttraumatic stress disorder, and alcohol dependence. These disorders, along with his genetic predisposition for mental illness (attributable to an extensive family history of suicide), contributed to Hemingway’s instability, love affairs, and eventual death by suicide.
