The Sorrows of Young Werther by Goethe
German Romanticism at it's finest. Dark but so beautiful. Very NFP.
Wuthering Heights by Emily Bronte
A family saga and romance novel filled with wit and wisdom. It's about more than just Cathy and Heathcliff. Hands down one of my favorite books ever. Emily Bronte was an INFP.
Anna Karenina by Leo Tolstoy
Russian Realism, gritty and satirical, a study of human nature, but also very darkly romantic and very NF.
Pride and Prejudice by Jane Austen
Hilarious, crisp writing. The quintessential "comedy of manners." Just a pleasure to read.
The Tropic of Cancer by Henry Miller
Banned in English speaking countries for 22 years, this lyrical, poetic, pornographic story is based on Miller's real life love affairs and his experiences living on the streets of Paris.
also anything by F.Scott Fitzgerald for a social overview of the 1920s in the U.S., and Agatha Christie...she really is the queen of crime.
