The Marcia part of the story is just bananas, you couldn't make it up. You wouldn't think it was possible for her contributions to be so minimized.

That's one of the main reasons I still see George's portrayal of himself as an easy-going, "hey it's just a kid's story" guy as a lie. Instead, he comes across as a petty, ego-maniacal control freak.

Marcia finally has enough of his behavior and he then spends decades trying to write her out of history. Truthfully, it's beyond disturbing.
