Hard to imagine this not coming across as either a hatchet piece or a mild hagiography. She was such a weirdo in the end that accurately portraying the last few years(which are the most interesting) would almost necessarily come across as a hit piece.
From what I understand she pretty much alienated everyone else involved in American Atheists and its hard to make someone who said:
"One could call this a postnatal abortion on the part of a mother, I guess; I repudiate him entirely and completely for now and all times ... he is beyond human forgiveness
when her son became a christian seem sympathetic with out ignoring it.
