Having created it in the first place, the wizards of Unseen University feel vaguely responsible for its safety. They know the creatures who lived there escaped the impending Big Freeze by inventing the space elevator - they even intervened to rid the planet of a plague of elves, who attempted to divert humanity onto a different time track. But now it's all gone wrong again - Victorian England has stagnated and the pace of progress has slowed right down. Unless something drastic is done, there won't be time for anyone to invent spaceflight and the human race will be just another layer in the bedrock.</p></div> Ebury Press 9780091898236 R0ViQgAACAAJ eng General Science Space Science Cosmology Life Sciences Evolution Discworld Fantasy Fiction
