LOSE THE STARS-
OR LOSE EVERYTHING!

Spacer Chan Dalton is torn between two masters. The pacifist aliens who hold Earth under Quarantine want him to find out why their starships have been disappearing in the Geyser Swirl, the Bermuda Triangle of the galaxy. Earth's military, which has secretly discovered a way to break the quarantine, assumes that someone out there is making ships vanish, including Earth's, and wants Dalton to find the culprits and hopefully stop themwith extreme prejudice, if necessary.

The trouble is, the aliens hold the taking of intelligent life, even in self defense, to be the greatest of sins. It was Earth's violent ways (in defense of the damned pacifist aliens!) that led to the quarantine in the first place-and if Dalton is forced to fight, it will unveil, and so destroy, Earth's final chance to reach for the stars again.

So when Dalton does indeed discover the hostile invaders responsible for the lost starships, he is faced with an impossible decision: Fight and lose access to space forever; or allow a rapacious enemy to run riot over all that he holds dear....

Charles Sheffield, a mathematician and physicist, is a past president of both the American Astronautical Society and the Science Fiction Writers of America, and the chief scientist of the Earth Satellite Corporation. He has published over a hundred technical papers and monographs on such subjects as nuclear physics, gravitational field analysis, and general relativity, and an equally large body of popular science articles for the layman. He serves as a science reviewer for several prominent publications.

In science fiction, Dr. Sheffield has received the coveted Nebula and Hugo Awards, as well as the John W. Campbell Memorial Award for his novel for Baen, Brother to Dragons.

He is also the author for Baen of Borderlands of Science: How to Think Like a Scientist and Write Science Fiction, which is both a nonfiction survey of current scientific frontiers and an explanation of how a science fiction writer can write SF using bona fide scientific knowledge. Which is just the sort of SF that Dr. Sheffield has been writing for some time now, to the resounding acclaim of readers and critics alike.
