Query: Badly Flawed.

I wanted to like this book; but despite the reasonable amount of research that went into it, the author ignores so much of the evidence and invents so many of her own fantasized views about Joan (some of which are merely repetitions of the slander levelled against her by her enemies) that it qualifies as distortion rather than history. Try one of Regine Pernoud's books (offered here at Amazon) instead.
