Bear Went Over the Mountain
William Kotzwinkle’s Bear Went Over the Mountain (©1996)
“Once upon a time a big black bear discovered a manuscript under a tree. He read it, and decided it wasn't bad. Borrowing some clothes from a local store and the name Hal Jal from the label of his favourite food, he headed to New York to seek his fortune. There he took the literary world by storm.” (Synopsis from http://www.fantasticfiction.co.uk/ )
