Mark Twain's autobiography coming out!

He requested his 5,000 pages of notes be held for a century after his death, and we are now at that point.

If you're familiar with his take on not just organized religion, but metaphysics/belief in his later life, especially as expressed in "The Mysterious Stranger," this could be VERY readable, not to count talk about a "slut" in his life, for whom he once bought an electric vibrator and with whom he had a relationship of five years after his wife died before a falling out.
