Just about anything by Mark Twain. Though if you want just one choice to start, here's a hint:
"All modern American literature comes from one book by Mark Twain called
Huckleberry Finn." -- Ernest Hemmingway.
I just finished reading
"Three Men in a Boat" published in 1889 by Jerome K. Jerome. Wry British humor of the day. I read it to satisfy an itch delivered 50 years ago when I read Robert Heinlein's
"Have Space Suit, Will Travel" (a classic book of another sort worth reading) that began:
You see, I had this space suit. How it happened was this way:
“Dad,” I said, “I want to go to the Moon.”
“Certainly,” he answered and looked back at his book. It was Jerome K. Jerome’s Three Men in a Boat, which he must know by heart.
Later in Heinlein's story, the father character says:
"Reminds me of this passage I'm reading. They're trying to open a tin of pineapple and Harris has left the can opener back in London. They try several ways." He started to read aloud and I sneaked out-I had heard that passage five hundred times. Well, three hundred.
I just had to read the book to find out how they eventually opened the tin of pineapples.
Anyway, there are the classic classics: the
Iliad and the
Odyssey. No need to read them in the original Greek.
Naturally, as a pilot, some Jules Verne would be appropriate (hard to avoid Hollywood taint when reading his original books) but
"Robur the Conqueror" could be added as a topical classic. Don't let it give you any ideas!
