STAMPING BUTTERFLIES tells the story of two dreamers. One, a would be assassin in tomorrow's Marrakech. He aims to kill the US President and holds in his head the secret to a faster-than-light drive. The other, a Chinese Emperor, ruler of 148 billion people on an immense Dyson sphere thousands of years in the future. Each believes they are dreaming the other. One must change the future, one must change the past. Both have only days to live. This is a fast moving unusually well written SF novel of ideas. Ideas that will change the reader's perception of time and fate. Ideas from the cutting edge of hard science. It is peopled with vivid characters and evocative of Marrakech, where the author has lived.
