From the dust jacket:
The beleaguered London of 1898 has barely had time to asses the injuries of recent conflagrations in the lower class districts when a new threat arrives, falling from the upper atmosphere in gargantuan metal cylinders that leading scientists claim have travelled from the planet Mars! Once again a call goes out through the channels of British Military Intelligence to an improbable group of champions: The League of Extraordinary Gentlemen.
