Amerigin.. I never knew of that. Is it fact or allegation?

Okay..I did a search and evidently it is mostly true. The scandal didn't break until 2014, and she died in 1999.
That she was lesbian doesn't surprise me after the many stories featuring women, but since most of my reading of her stuff was before 2014, I never heard of the scandal.

In my head I have to separate my enjoyment of the Darkover series from her personal life... but it sure is a shock.
