If you like science fiction, I would recommend Mike Resnick.
He's perhaps not as popular or well-known as other authors, but I really like his stories. Important themes are Africa, imperialism and colonialism.
He certainly received some recognition too:

Quote:

Resnick has been nominated for 37 Hugo Awards—a record for writers—and won five times. Except for 1999 and 2003, he has received at least one nomination every year from 1989 through 2012; then, after dropping off the ballot for 2 years, he was nominated again in 2015.

He has won numerous other awards from places as diverse as France, Japan, Spain, Croatia, and Poland. He is first on the Locus list of all-time award winners, living or dead, for short fiction, and 4th on the Locus list of science fiction's all-time top award winners in all fiction categories.

Then there's also this anecdote:

Quote:

Resnick was a regular contributor to the SFWA Bulletin published by the Science Fiction and Fantasy Writers of America. In 2013, articles he wrote for the Bulletin with Barry N. Malzberg triggered a controversy about sexism among members of the association. Female authors strongly objected to comments by Resnick and Malzberg such as references to "lady editors" and "lady writers" who were "beauty pageant beautiful" or a "knock out." In the next issue, Malzberg described their critics as "liberal fascists". The Bulletin editor Jean Rabe resigned her post in the course of the controversy, and the magazine was relaunched under new management.

I can recommend these stories specifically:

Kirinyaga (Hugo Award winnner)

Quote:

A series of parables about one man's attempt to preserve traditional African culture on a terraformed utopia.

The prologue and eight chapters of the book were each originally sold as a short story. The book and its chapters are among the most honored in science fiction history with
67 awards and nominations including two Hugo awards.

Seven Views of Olduvai Gorge (Hugo Award winner, Nebula Award winner)

The 43 Antarean Dynasties (Hugo Award winner)

Birthright: The Book of Man


If you like horror, there's always good old H.P. Lovecraft.
His style is probably a bit old-fashioned, but his work is hugely influential, despite his critics claiming that he was a sexist, racist and anti-Semite.
(Why do they claim that? Because it's 100% true. )
Be aware that his work is not red pilled, it's a deep, dark black pill.
It's horror, after all.
