Does On the Beach count?
Later books focus more and more on the south.
Another fantasy one: the continent of Roshar, setting of Brandon Sanderson’s ongoing *The Stormlight Archive *series (The Way of Kings, Words of Radiance).
(Highly recommended, incidentally, if you haven’t read them yet)
Y’know, technically WATCHMEN is partially set on the Southern Hemisphere of Mars. (And when they’re on Earth, it’s partially set in Antarctica.)
Some of the Fremen projects were in the Southern hemisphere of Dune. Not much said about them, tho
What would the Ringworld be?
Mostly I’m just wondering how many SF authors are thinking outside their box. Apparently very few.
Not a sphere, so no hemispheres.
BTW, in the OP, I wasn’t sure about the Inheritance Trilogy. In rereading one of the books, I noticed a data item that was pretty conclusive. The High North was a locale that grew coffee. That pretty much settles it.
The continents in that world seems to be based roughly on Australia and that region. Or maybe the word should be inspired. Semn is the big continent (Australia in this case, but probably bigger and definitely further south, so probably no deserts); the High North is smaller (New Guinea, but bigger), the Archipelago is to their east (South Pacific islands), the Meroland is further east (so maybe South America?).
Beam Pipers Terro-Human Future History series posits an expansionistic human race from Australia, South Africa and South America because the north was devastated by nuclear war. There’s at least one story where explorers choose to land in the Southern Hemisphere of a new planet because that’s ‘right’ to them.
There are a few references in Marion Zimmer Bradley’s Darkover series that the sole inhabited area of the planet is in the southern hemisphere, most explicitly in The Planet Savers which is neither the best nor the most well known of the novels. However, all maps of the planet are oriented with the colder bits at the top… which may mean “south” is towards the top of the map or, like the Himalayas on Earth, it’s on a part of the planet where, due to high mountains, it gets colder as you go north towards the equator because you’re going upwards.
The trilogy The Stone Dance of the Chameleon is set on the continent of Antarctica in a prior geological age when it is a lush temperate to tropical climate. OK, sorry, that is Earth, isn’t it?
