Scout's Law. Scout, #4

After two thousand years of isolation, the lost colony world of Aashla has re-established contact with the rest of galactic civilization. Princess Callan and her royal consort, Terran Scout David Rice, made that happen. Now, they lead a mission to ensure that Aashla's unique culture isn't overwhelmed by the vast, technologically advanced Terran Federation. Then a routine inspection of Federation scientific outposts unearths a mass grave.
Shortly after, an unnatural storm knocks David and Callan's airship from the sky, forcing them to confront their worst nightmare. Someone has smuggled forbidden galactic technology onto Aashla, and the trail of murder and destruction has only just begun. Can David and Callan stop the fiends from destroying their world? Grab a copy of Scout's Law and discover the answer! I've enjoyed this series immensely.
They...are plain and simple adventures. But plain and simple adventure yarns are quite satisfying at the end of the day. Doug Irvin, Amazon reader
