Uneasy lies the head. In just a few months, Alacrity Fitzhugh and Hobart Floyt had claimed Hobart's inheritance from the ruler of a small interstellar empire then returned to Earth and toppled its government. They'd also become good friends. But Alacrity had more important goals than bodyguarding Hobart - he wanted command of the fabulous White Ship, the starship designed to track down the secrets of the ancient and powerful Precursor aliens. Yet it took only a few minutes at the White Ship's helm for Alacrity to learn that a captain's problems can be tougher than the "real work" of a knockabout Spacer - and that solving them could cost a piece of his heart.

A mission to Hell.... Just yesterday, Sergeant Gil MacDonald and his APC crew had been fending off an ambush in a Viet Nam jungle. In the middle of the firefight, some kind of magic spell had transported them to this Fantasy Land complete with flying dragons, wizards, crazy castles, and dispossessed princes. They would stay trapped here forever unless they could rescue the sorceress Gabrielle. Master magician Amon held her captive in his palace; and to reach her, Gil and his men would have to infiltrate Hell itself!

The flies in the ointment. Once upon a time, the dying ruler of a small interstellar kingdom made a minor Old-Earth bureaucrat named Hobart Floyt the surprised inheritor of an interstellar spaceship. And that was wonderful, for in those days, when mankind was again expanding into the galaxy, a private spaceship was a license to coin credits. There were just a couple of minor problems. The dead ruler never told Floyt how to find the ship, the bureaucrats of Earth wanted the ship for themselves, and someone kept trying to murder Floyt and his friend, Alacrity Fitzhugh....
