This very well written account of Tolkiens life as a boy, a husband, writer and professor takes you away from where you are into the heart of Tolkien's being. It covers his writtings in depth, the making of languages, of peoples, of maps. But also his academic life, Beowulf, the Islandic Saga, the inklings, his relationship with C.S. Lewis, his day-to-day habits, his children, his religion. It breathes a wonderful inspiring atmosphere. I've read is several times now, and it still moves me.
This biography is a gem in its own right. You won't regret buying it.
