I would agree that OSC is one of the better old Sci Fi writers with a couple of reservations.Orson Scott Card. My absolute favorite writer. Best work is the Ender's Game saga. 9 books total.
Sounds interesting. Might have to add that to my future Fantasy reads.Another great fantasy saga is The Mists of Avalon, by Marion Zimmer Bradley. A beautiful and really refreshing version of the arthurian legend through the perspective of the female character, mainly. It also explores the clash of two worlds (christianity and paganism) and the consequent cultural shifts. Highly recommended.
