Four Day Planet & Lone Star Planet: Science Fiction Novels

"Four-Day Planet" is set on a planet called Fenris, where extremes in climate have resulted in an extremely small population with very few off-world contacts. The protagonist is a 17-year-old reporter who fights to overturn the corrupt 'government' and coercive mercantilist monopoly on 'tallow-wax', the sole export from Fenris. "Lone Star Planet" is set on New Texas, where everything from cows to nuts is prefixed. Silk, the unwilling, banished replacement for the Solar League's former ambassador, must solve the murder and stave off an anticipated invasion by the Srauff, a canine alien race, while preventing his own assassination on a planet where the killing of politicians is acceptable, if they "had it coming."
