I liked this book. It's mostly the non-fiction story of Joan of Arc, with some Mark Twain fiction added to it to make it a great and vivid story. It got just a little long in the middle section, the period of war/battles (vs. the first period of growing up or the third of her capture and trial), but I really enjoyed it. What an amazing character she was! Here's what Mark Twain said about this book:
"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."
