A group of astronauts find themselves responsible for continuing the human race in G. F. Sheridan's engrossing sci-fi novel, Reach for Mars!

Nick Watson and Drew Hunt started out together as fighter pilots for the United States Navy Air Wing-and now they're best friends.

These buddies are in for the trip of a lifetime when they're asked to join four astronauts on a mission to help terra-form Mars, making it hospitable for human life.

Blasted into space, they hardly have time to get used to their new surroundings before they witness the horrifying sight of Earth being destroyed behind them.

Alone in the universe, Nick, Drew, and the other astronauts have no choice but to continue on to Mars and attempt to complete their mission-with only their limited supplies and equipment to help them.

While exploring their new home planet, however, it suddenly seems as if their luck is changing when they stumble across a deserted underground city. With hopes that they can repair its support and environmental systems, the astronauts get to work.

But questions remain. Who built the city? When and why was it deserted? And will the original inhabitants ever come back?
