A Quiz Question For Sci-Fi Fans

[Spalding]

Three writers, whose last names are starting with the same letter, wrote sequels (each - just one novel) to one famous sci-fi novel cycle. All three full titles of sequels contain the title of that cycle. Name these three authors, please.

I rather assume you know the answer, so this isn't a book search matter, which is designed, strangely enough, for people who are searching for specific books, the titles of which they have forgotten.

I'm therefore moving it to the SFF Lounge temporarily, though I can see it might end up in Playrooms, if it takes off.

No, I don't know the answer and I have to get it in 5-6 hours.
