What a terrific collection. I, too, was a Hardy Boys fan. Read all 40 (?? That many!?!?). Could not get through Ulysses, however hard I tried. Moby Dick and all of Conrad ("the horror, the horror!"). Dumas Malone's Jefferson (no, really!).
Endurance. The Last Place on Earth.
SF: Ender's Game and the next two, but couldn't go beyond that. Snow Crash. All of LeGuin, especially Wizard of Earth Sea. McKillip: Harpist in the Wind series; Forgotten Beasts of Eld. And should we have a contest on who's read Lord of the Rings more?? (hint: > 30 -- it's lonely on the frontier...).
Oh. Iliad and Odyssey a couple of times each. And, of course, Huck Fin X 4 or 5. Truly the Great American Novel.

PS: and the Aubrey/Maturin series by O'Brian (Master and Commander etc.) -- truly great.
