"I like Joan of Arc best of all my books; and it is the best; I know it perfectly well. And besides, it furnished me seven times the pleasure afforded me by any of the others; twelve years of preparation, and two years of writing. The others need no preparation and got none." -- Mark Twain Twain considered this book -- his last finished novel -- to be his most significant. Perhaps it is; certainly it's delightful -- but then, in retrospect, everything Twain did is good cause for delight.
