Charles Sheffield is a mathematician and theoretical physicist by training. His doctoral work was on Einstein's Special Theory of Relativity. Currently Dr. Sheffield works as chief scientist for the Earth Satellite Corporation, a Washington, D.C.-based firm that specializes in the analysis of data gathered from space. The author of thirty previous science fiction novels, including" Cold as Ice" and" The Ganymede Club" from Tor, Sheffield lives in Silver Spring, Maryland, with his wife, author Nancy Kress.
The war between the inner planets and the asteroid belt is 25 years in the past; travel is common throughout the solar system, and human interests have spread as far as the moons of Jupiter. When a handful of very special people find themselves drawn by apparent circumstance to the underground colony on Europa, the seeds of a conflict long thought to be ended begin to bear unexpected fruit. The author of ``The Heritage Universe'' series combines a wealth of expertise in theoretical physics with a gift for storytelling to create a novel of hard science and political intrigue that belongs in most sf collections.
"Sheffield's uncommon vision and storytelling skill will keep you on the edge of your seat."--David Brin "Fits comfortably on the shelf with Clarke and Asimov and Heinlein. He writes classic stuff."--"Analog" "Written at the level of Arthur C. Clarke at his best--with deft characterization, pellucid handling of scientific questions, good world building and real wit--this is arguable Sheffield's best book yet."--"Booklist"
