'The human consciousness had now widened so alarmingly, was so busy transforming everything on Earth into its own peculiar tones, that no art could exist that did not take proper cognisance of the fact. Something entirely new had to be forged.' The time traveller Bush's adventure takes him through 1930, 1851, the Jurassic and 2093, on the way exploring a modern crisis that remains our own. In Brian Aldiss's tale of time travel, the fiction is once again as psychologically imaginative as it is scientific, an idiosyncrasy of Aldiss's future visions that, over time, have proven remarkably prescient.
