The stargods trilogy

"Operating on the wrong side of interstellar law one time too many, the three O'Hara brothers find themselves in a life-or-death flight from intergalactic police forces. In a last desperate escape attempt, they stumble across what must be a lost or abandoned colony world. Forced to bring their shuttle down in search of repair facilities, the O'Haras encounter humans who have returned to a hunter-gatherer level of society. Here is a place where technology can make them seem like gods-- a land where they will remain trapped unless they can find a way to mine and manufacture the things they need to repair their ship. They don't believe the legends about dragons and magic, and they are certain technology will see them through-- at least until they confront their first dragon and feel their own unique powers expanding beyond their control.... Here, together in one volume for the first time, are the three novels which reveal the truth behind the legend of the Stargods, the events which changed the future of an entire world"--Page 4 of cover.
