One of the best gifts I ever got was when my dad plopped down a big box full of old classical adventure novels (Twenty Thousand Leagues Under the Seas, King Solomon's Mines, Captains Courageous, Three Musketeers, Count of Monte Cristo type of stuff) and I devoured all of them over the course of the next year or so. I'm sure I would appreciate a lot of different things about them if I read them now, but they certainly held up in terms of being engaging in spite of them all being 100+ years old by the time I got my hands on them.
