A devoted J.R.R. Tolkien fan from an early age, Thiel is equally enamored with Kirill Eskov's The Last Ringbearer, a retelling of The Lord of the Rings in which Sauron is a beleaguered victim and the elves are bellicosely bent on world domination. "Gandalf's the crazy person who wants to start a war," Thiel explains, "and Mordor is this technological civilization based on reason and science. Outside of Mordor, it's all sort of mystical and environmental and nothing works. Anyway, it's really clever."
