Twice Upon a Time

"Twice Upon a Time” is a
wonderful story of space opera and time travel. Because of the long
years it took to travel between the worlds of the galaxy, interplanetary
peace could only be maintained by a small band of men known as The
Deathless Legion. And of these cosmic policemen, Chaan Fritag of Earth
was the first to cross the path of the man who wanted to be Napoleon of
the stars.
