Book sales of the works of J.R.R. Tolkien keep pace with those of the Koran and the Bible. TV companies pay hundreds of millions to the Tolkien Trust to make adaptations of his work. In the UK, he routinely tops the list of the nation's favorite authors. An estimated 2 million war gamers use The Lord of the Rings figurines in their RPG. It is incontestable that Tolkien is the most influential Catholic writer of the last century. Tolkien, Philosopher of War fills a gap in the scholarship. It is the first book addressing the philosophical and theological understanding of war in Tolkien and will interest readers, the philosophy and theology of literature, war studies, Tolkien Studies, English studies, political theory, and aesthetics.
