The final exam for Dr. Matson's Advanced Survival class was meant to be just that: only a test. But something has gone terribly wrong...and now Rod Walker and his fellow students are stranded somewhere unknown in the universe, beyond contact with Earth, at the other end of a tunnel in the sky. Stripped of all comforts, hoping for apassage home that may never appear, the castaways must band together or perish. For Rod and his fellow survivors, this is one test where failure is not an option....
Robert Anson Heinlein was an American science fiction writer. Often called "the dean of science fiction writers", he was one of the most popular, influential, and controversial authors of the genre. He set a high standard for science and engineering plausibility and helped to raise the genre's standards of literary quality. He was one of the first writers to break into mainstream, general magazines such as The Saturday Evening Post, in the late 1940s, with unvarnished science fiction. He was among the first authors of bestselling, novel-length science fiction in the modern, mass-market era. For many years, Heinlein, Isaac Asimov, and Arthur C. Clarke were known as the "Big Three" of science fiction. ([Source](http://en.wikipedia.org/wiki/Robert_A._Heinlein).)
