I like Marion Zimmer Bradley's Darkover series. It's about a group that crash lands on this colder, slightly darker planet (with 3 suns, go figure), that because of the crash, loses contact with Earth and is forgotten about. The planet's culture eventually develops to the point it has completely forgotten or rewritten its origins and individual cultures for different areas have developed. Then Earth re-makes contact with it. It's what I'd call fem-lit as there is definitely a feminist flavor to it, but not so much that I would find it distasteful or anything. Many books in the series too, so pretty fun to go through.
