Peter Raeder was an ace pilot until a battle cost him his hand -- and his right to fly the fighter ships he loved. So he became Flight Engineer on the fast carrier Invincible, a crack new ship with a picked crew, ready to fight the fanatical Mollies and their spiderlike alien allies. On his first mission, he faced pirate raiders, attacks by Mollies and a hidden saboteur on board who came close to destroying the Invincible before Raeder unmasked him.

Unfortunately for Raeder, his heroism didn't follow the rulebook, and his reward for saving the ship was a reprimand and a deskbound assignment -- a fate worse than death for a born spacehound like Raeder. Then a less rulebound General offers Raeder an escape: command of a hidden base deep in Mollie-controlled space from which ships, posing as space pirates, will harry Mollie shipping, like the seagoing privateers of Earth's past. And Raeder finds a dangerous mission preferable to exile to an office cubicle ... even if his chances of surviving are very nearly zero.
