2. The Choir Invisible by James Lane Allen (1849-1925)
"The hero is John Gray, a schoolmaster and idealist, who, disappointed in his love for Amy Falconer, a pert, pretty, shallow flirt, gradually comes to care for Mrs. Falconer, her aunt, a noble woman in reduced circumstances, who with her husband has left a former stately home in Virginia and come to live in the Kentucky wilderness. She loves him in return with a deep, tender passion that has in it something of the motherly instinct of protection; but, her husband being alive, she conceals her feeling from Gray until after he has departed from Lexington and settled in another State. She then writes him to say she is free—and he replies that he is married. But he tells her in a final letter that she has remained his ideal and guiding star to noble action. The romantic atmosphere and the ideal cast of these two leading characters make the fiction very attractive; and the fresh picturesque descriptions of pioneer life in Kentucky give the tale historical value."

10. The Honorable Peter Stirling by Paul Leicester Ford (1865-1902)
A novel of the late 19th century realism movement, detailing petty local politics in Brooklyn, based on the author's own abortive attempts to enter politics. Trivia: mainly became a best-seller due to a belief that the main character was a version of Grover Cleveland. (The author always denied this but the case seems strong when matched against Cleveland's life story; Cleveland himself was known to dislike the book!)
