For a tale that helped jump start the genre of science fiction in 1919, this is a surprisingly fun story. Sure, the rationale for the skyscraper going “runaway” is a bit hokey, but they didn’t have quantum mechanics back then, just H.G. Wells. It has that sensibility of the era it was written, so be forewarned, but give it a read.
Every sci-fi fan should experience the beginnings, so they can hopefully more appreciate the good stuff they have now.
