About this book

In Ray Bradbury’s classic time-travel short story, a wealthy hunter joins a guided safari millions of years into the past to shoot a Tyrannosaurus rex. Strict rules are meant to prevent any change to history, but a single misstep—crushing a butterfly—unleashes unforeseen consequences when the travelers return to the future.

Setting: A near-future United States (year 2055) and the prehistoric jungle during a commercial time-travel safari to the age of dinosaurs
