Fowler, Therese Anne - Z: a Novel of Zelda Fitzgerald
This novel focuses on the life of Zelda: dancer, writer, and famous flapper who married Scott Fitzgerald. The Fitzgeralds were considered the couple of the twenties. Zelda and Scott spent time in Paris in the same social circle as Hemingway and his wife where the hard-drinking and romances took a toll on both marriages. If you've read about Zelda in Scott's or her own writing, this fascinating, multi-talented person will intrigue you.
Hart, Lenore - The Raven's Bride
If you love Edgar Allen Poe's famous poem "Annabel Lee", this novel about Poe's doomed wife and first cousin, Virginia, will interest you. The Poes married when Virginia was thirteen and E.A. was twenty-seven; her mother signed a document that she was of age. Like Hemingway, Poe was a big drinker, and Virginia had to put up with drunkenness and poverty. Another story of a literary marriage where the wife was both muse and care-giver.
Hemingway, Ernest - The Sun Also Rises
This is often considered the most famous novel of the "Lost Generation", that crowd of artists, musicians, and writers who left the U.S. during the 20s to live an expat lifestyle in Paris and other cities. Jake Barnes, a jaded WWI vet, travelled from the bars of Paris to Spain for the spring bullfights. Hemingway describes the expatriate lifestyle amid the violence, camaraderie, and life and death risk for bulls and men.
