If he survives, hell just may freeze over. The savage Hammer Worlds are not only near invincible but almost certain to win their war to crush the Federated Worlds and control humanspace-unless the Feds can find and destroy their secret antimatter warhead facility. Only dreadnoughts, the lone Federated ships able to withstand antimatter missile attacks, can do the job, and only Lieutenant Michael Helfort has the skill to lead them. But skill may not be enough, because Helfort is more than the newly appointed captain: He's a hero, and this means that his own senior officers want him to fail-and that the enemy's kingpin wants him dead. Helfort's early victories merely intensify everyone's determination. No action is too low, no price too high, to bring him down-with treachery, or betrayal, or an offer he can't refuse, even if it means selling out his own side.
