I read non stop as a kid and young adult, not nearly as much any more. My grandmother got me reading at the age of 4. Standouts are;
"The Machine Gunners" by Robert Westall. I'd think a modern school would probably remove this one, but I found it fascinating as a kid in middle school.
"The Hobbit/Lord of the Rings" - I still have my 1977 boxed set. I read the entire thing in three days.
"Patton: Ordeal and Triumph". My copy went with a staff member who worked for me when he deployed to Afghanistan in 2007. It was in his pocket when the IED sent him to his eternal reward.
Of course, the classic we had to read in school and still fascinates me today, "Alas, Babylon"
My mother collected Readers Digest condensed books and one I still have today, with the 1968 abridged copy of one of the greatest war novels I've ever read, "Once an Eagle" by Anton Myrer. MANY years later I finally found the video of the mini series they made from the book, and after about 20 minutes I turned it off in disgust - they ruined it. I bought an unabridged copy many years later, great book.
