I'm not sure what H.G Wells was intending with this book. As science fiction, it's rather poor. As a story, it's a bit of a 'Boy's Own' adventure. As a satire of the archetypal 'Brit abroad' and social comment, it's rather enjoyable, I'm just not entirely sure that was Well's intention.
Mr Cavor, a scientist, invents a substance that negates gravity and builds a sphere that will travel to the moon. Unfortunately, he takes Mr Bedford, a failed entrepreneur with him which causes no end of problems.
