Terrible idea: a scifi story set in a early-20th century idea of the solar system.
Mars is a dying desert covered in canals to bring water from the poles to the sand cities at the equator.
Venus is a humid jungle/swamp full of strange beasts.
Both are fully habitable by humans with no more gear than you'd need to cross the Sahara or venture into the rainforest.
The trick? This is actually a distant future realistic setting. We terraformed the planets specifically to be like that.
@foone but is it high tech / futuristic or does it seemingly takes place in a strange alternate 20th century until you find out it's like 30th century?
@Andrew yeah. It turns out it's the 20th century, Tranquility Calendar.
It's been 1923 years since Apollo 11
