Marion Zimmer Bradley is a fantasy and science fiction writer, although The colors of space is the first science fiction book I read by her, I read many of her fantasy novels of "the Avalon" series, starting with the 1000 pages novel The mists of Avalon (which tells the story of King Arthur from a feminist perspective focusing more on the Priestesses and druids point of view and the celtic culture and religion), and falling in love with it, then following it with 3 of the 4 novels that happen in the same era but are before the story of king Arthur, and with the same perspective.
Reading The Avalon books made me want to read all what she wrote, she has a small series of books about Atlantis..in Avalon, the legend is the first priestesses and druids who came to England where the survivors of the drowning of Atlantis, so I really must read these books.
She also has a big series of science fiction novels called The Darkover
During the early years of space exploration and colonization, Earth-based humans planted a colony on Darkover, a planet which circles a red giant. Through an unpreventable mishap, contact between the colonists and Earth was lost. The ethnic background of the colonists was Celtic and Spanish, and included both pro-technology scientists and techophobic back-to-nature zealots. (...)
Wow!! Science fiction book with a celtic theme, I would sure love these books :-)
It's this matriarchal world that really attracts me, and seeing all the events from the heroines' point of view, although this was not the case in The colors of space, in which the female character had a trivial role in the events.
