Fess, Rod Gallowglass's faithful cybernetic stallion, has had a long life and many grand adventures. But what about the masters he served before Rod Gallowglass? What about the young, spoiled joyrider? Or the revolutionary hero? Or the crew of a pirate ship? Over the hundreds of years its been operating, the epileptic robot has served masters selfless and selfish, sensible and senseless, from frontiersmen to fugitives, prospectors to patriarchs. Now the Gallowglass children are about to hear the truth... straight from the horse's mouth!
