America became home to the huddled masses seeking opportunity in a new land. In our future homeless teenager Gary Grime has a seeks a similar opportunity - and he's willing to do whatever it takes to go to Mars, no matter how slim the chance. Hundreds of thousands seek to travel in hibernation, steerage class, to reach the new world. But the odds of surviving the process first depends on being young and healthy enough to survive the experience... Worse, reaching Mars is only one challenge, because the odds of survival grow worse, not better, if they make it to the subterranean colony on the inhospitable planet - a world that could take decades, if not centuries to make habitable.And Mars will do everything it can to kill him and all those he will come to love and depend on... if his fellow desperate colonists don't first.Welcome to D.H. Aire's somewhat satiric tale of the mass immigration to Mars experience.
