"When the solar system's key asteroid mine is seized by revolutionaries, it puts the secret mission of the spaceship Ulysses in jeopardy. Without a refueling launch from the asteroid, the survival of the ship and its crew is uncertain. The safest course for the Ulysses? Abandon the mission and limp home. But Cal Scott, captain of the Ulysses, is an astronaut of the old school and failure is not an option. He has a plan: head straight for the asteroid belt and get their fuel--one way or another."--Back cover.
