There is a link to fanfic for virtually every TV series, as well as movies, books, comics, etc.

Much of the Golden Girls fic there is "femme slash," but I like "And Then There Were Two." It is about Rose and Blanche considering their options after the deaths of Sophia and Dorothy (which are based on the real deaths of Bea and Estelle.) Apparently, neither Golden Palace nor Dorothy's second marriage ever happen. This author also "writes out" Miles, but in a way I find more consistent with Rose's attitude, and all the girls' on the show.
