I was going through my books thinking about books I would like to reread.
Susan Elizabeth Phillips-- I've reread the Chicago stars series several times.
Elizabeth Peters: Amelia Peobody series and others.
Robert Heinlein: The Lazaerus Long books, Farnhams' Freehold, others
M.M. Kaye: any and all
Andre Norton: Witch World Series. Haven't read it for while, might open it up soon.
Elizabeth Goudge: Little White Horse --children's book but still beloved.
CS Lewis Narnia series: ditto
Marion Zimmer Bradley: The Avalon Series
Ursula LeGuin: Earthsea
There are others, I just need to wander through the library
