From Up And Down
Circumpolar! (Twin Planets, volume 1)
By Richard A. Lupoff
1984’s Circumpolar! is the first volume in Richard A. Lupoff’s Twin Planet’s duology.
It has long been known that the Earth is a flattened toroid. Vast ice walls bar the southern (outer) edge of the planet. Fierce winds make passage through the hole at the northern (inner) region nearly impassable. Therefore, while this side of the Earth — the side with Eurasia, the Americas, and all the other familiar continents — has been mapped, nothing is known of the other side.
Mrs. Victoria Woodhull Martin offers fifty thousand dollars to the first team to somehow reach and return from the other side of Earth.
Two aviator teams undertake this historic challenge.
