This classic work of science fiction is widely considered to be the
ultimate time-travel novel. When Daniel Eakins inherits a time machine,
he soon realizes that he has enormous power to shape the course of
history. He can foil terrorists, prevent assassinations, or just make
some fast money at the racetrack. And if he doesn't like the results of
the change, he can simply go back in time and talk himself out of making
it! But Dan soon finds that there are limits to his powers and forces
beyond his control.
