The Land of the Changing Sun

This is late-19th-century speculative adventure at its most exuberant. When aeronauts Harry Johnston and Charles Thorndyke survive a catastrophic balloon crash, they wash up on an island that defies everything they know. What they find there is neither wilderness nor any nation on their maps, but something far stranger: a civilization operating under radically different environmental conditions, where the sun itself seems to behave in uncanny ways. The opening sequence, with the two men desperately launching themselves from a failing craft into the open sea, is genuinely thrilling. As they explore, they encounter silver objects and signs of an advanced society that challenges their understanding of the world. Harben wrote this at science fiction's infancy, when authors could imagine freely without the weight of later scientific consensus. For readers who wonder what the future looked like before it was written, this is a window into an age when anything seemed possible.
