Ray Bradbury had many favourite books, but Edgar Rice Burroughs' John Carter: Warlord of Mars series was the one that made him an author.
"[They] entered my life when I was 10 and caused me to go out on the lawns of summer, put up my hands, and ask for Mars to take me home," Bradbury said. "Within a short time I began to write and have continued that process ever since, all because of Mr. Burroughs."
