The Dragon Circle. The Stargods, #2

With dragons you have to re-invent physics. In the world of The Dragon Nimbus, this second volume takes the three O'Hara brothers, and their long lost sister (who doesn't think of herself as an O'Hara anymore) through the intricate worlds of dragon politics, corporate politics, and family grudgesMark Kimmer (Kim), Martin Konner (Konner), and Mathew Kameron (Loki) O'Hara have been space faring smugglers and pirates almost all of their lives.
On the run, as usual, from the Imperial Military Police (IMPs) they fly through a rogue jump point and land on a lost Earth colony planet where dragons are real and magic works. They use their technology and new-found psi powers to free some slaves and cure a plague. The locals proclaim them the Stargods. Then they have to live up to it. They each have a separate agenda. But can they repair their ship in time to meet their appointments back in civilization? Only if the dragons allow it, they reinvent the laws of physics, and break their hearts leaving behind all those they have come to love.
