The editors of GQ have compiled a list of 20 notable books that you don't actually have to read, despite their inclusion on various must-read lists. For each one, they suggest a replacement. So:
Don't read: Slaughterhouse-Five by Kurt Vonnegut
Do read: Veronica by Mary Gaitskill
Don't read: The Lord of the Rings by J. R. R. Tolkien
Do read: Earthsea Series by Ursula K. Le Guin
Don't read: The Ambassadors by Henry James
Do read: The Rise and Fall of the Third Reich by William L. Shirer
Two editors independently recommended ditching Twain's Adventures of Huckleberry Finn, with Tommy Orange saying:
Mark Twain was a racist. Just read Adventures of Huckleberry Finn. He was a man of his time, so let's leave him there. We don't need him.
