Trojan Orbit, by Mack Reynolds and Dean Ing (epub/Kindle/pdf)
Island One, the U.S.'s first space colony and symbol of an American Renaissance, is in trouble. Low morale, shoddy workmanshpi, unexplained malfunctions, and avoidable accidents have become a way of life, and nobody seems to know why. Is in the Russians? Home-grown anti-tchnologists? Arabs afraid of cheap solar power from Space -- or something even more sinister? Only a detective from Earth can solve the mystery!
