I was a huge fan of Judy Blume's "Fudge" series, especially "Superfudge", when I was in grade school. In junior high it was "Indiana Jones and the White Witch" by Martin Caidin. In high school I was too busy transcribing video game music to spend a lot of time reading, but I enjoyed a couple books I read in classes, mainly "One Flew Over the Cuckoo's Nest".
