Synopsis: From the back cover of the Roc first edition: "Dawn in space comes from the fire within... For hundreds of years, humans have used the great engines of the alien Enamorati to propel their biggest starships, enabling millions to travel - and live - among the stars. As part of this alliance, the Enamorati jealously guard the secrets of their Engines' power. And a complacent humanity becomes dependent on their alien benefactors for survival.

Theirs is the first shot in a growing rebellion against the aliens. And their probes into the inner reaches of the Enamorati culture and mind will uncover the shocking secret of the aliens' technology - and set the stage for revolution..."
