Case of Cosmic Chaos [PDF ebook] 

Has extortionist extraordinaire Caleb Cassowary gone off the grid? Not hardly! He and his assistant Byzantia Bonobo escaped from Earth and landed on Biosphere X and Exoplanet Gaea, respectively. Caleb has persuaded the leaders of the Biosphere (Home World) with his plans for interplanetary conquest. As a first step, he proposes to attack Earth where it is most vulnerable – GPS. Byzz has taken on a new career launching satellites on Gaea. The Cassowary once again calls on her for assistance. What happens next propels Octavius Bear and his associates into a whirlwind of galactic uproar. Watch this space, literally!
