There's no turning back.
The year is 2085, and a new teen has arrived at Mars Experimental Station One, a colony built to test humans' ability to live self-sufficiently in an alien and hostile environment. Already in existence for ten years, "Marsport" is a functioning city of two thousand people -- with only twenty teenagers. These teens, part of the controversial Asimov Project, were hand selected from the billions on Earth and are always under the watchful eyes of the adults.
The newcomer, Sean, is a fifteen-year-old orphan who acts tough but secretly thinks he can't measure up to the others. His companions are Jenny, also fifteen, an ethereal blond whose frail looks belie her fierce intelligence, and Alex, a fourteen-year-old pilot in training who doesn't always know his boundaries. They each have reasons to doubt themselves...and distrust each other. But one thing is certain: Mars offers them something Earth never could. When the existence of Marsport is suddenly threatened, the group must overcome their fears and join forces, for their survival depends on nothing less.
