Sam Nicholson’s 1980 The Light Bearer is a standalone science fiction novel. It was Nicholson’s only novel and as far as I can tell, this was its only edition in any form.
Sam Nicholson is a pseudonym; the author is said to have been a certain Shirley Nikolaisen, about whom we know almost nothing. We don’t know why she stopped writing.
Stumbling over a planet populated by Bronze Age primitives, the so-called Space Givers saw only a world of rustics who would no doubt be overjoyed to be raised up to the galactic level. In short order the Space Givers discovered that the locals saw them not as paragons to be emulated but as sheep to be shorn. Having retreated to their orbital complex, the Space Givers embarked on a lengthy attempt to gradually civilize a world that considered Space Giver ideals laughable at best.
Many years later, at the great city of Mus-al-ram, Zeid the Light-Bringer offers the Space Givers hope that their project is finally bearing fruit.
