When I was growing up, there weren't a whole lot of books in the house, and I was a regular at the library. But we had one small set of book shelves with a fairly esoteric mixture of books that my mother had somehow collected over the years. These didn't interest me until I started reading science fiction, and remembered that a set of H.G. Wells filled most of one shelf. So I dived into The War Of The Worlds, The Time Machine, The Invisible Man, and The First Men In The Moon, because I had seen those movies. That, of course, led me to try a few others. I remember The War In The Air made a big impression, but I don't recall which other Wells books I tried.
Another shelf had a couple of big books that I would have considered intimidating before reading the Wells books. They were 100 True Stories Of The Great War and 100 True Stories Stranger Than Fiction. The war stories were often horrific, but also sometimes amazing. One scene that really stuck in my mind was a fighter pilot whose plane featured a machine gun with a drum magazine on top, mounted on the front edge of the cockpit so the pilot could reach up and pull the trigger. When the gun jammed, he stood up, holding the joystick between his knees, so that he could use both hands to wrestle with the magazine which was stuck (and he needed to remove it). Then when he slipped, the plane flipped over, so that it was flying along upside down, and the pilot was dangling outside the plane, hanging on to the magazine which he had been trying to get loose, and now fervently wished would stay stuck. I can't remember how he managed to get back into the cockpit, right side up. But he did live to tell the tale.
There were some other good books too: The Three Musketeers, Ivanhoe, probably others I have forgotten.
I find that remembering these books that I read nearly 60 years ago, I don't really recall the whole book, just certain scenes that made an extra-strong impression. The gentle tournament at Ashby (Ivanhoe) got extra credit because Ashby De La Zouch is a town not that far from where I grew up.
