I feel like this has strong potential for a plot to a sci-fi/fantasy thing
the book starts with the realization that astrology works on venus and then goes on to *why* does it work there, using equations worked out by people millennia ago who were definitely on earth at the time... right?
it's not the most fascinating plot out there but it's about on par with some of the cheap paperbacks we've found in the library's used bookshop
it has that kind of... mid-20th-century-sci-fi feeling to it
