TARRANO THE CONQUEROR is a wonderful early example of Space Opera, a subgenre of Science Fiction emphasising romantic and melodramatic adventure. A swift and sweeping interplanetary adventure presented as a tale of the year 2430 A.D. The story centres on the efforts of Jac Hallen and his friends to stop the evil Tarrano from taking over the universe. The DOCTOR FEATHER stories feature the mild-mannered scientific sleuth, Dr. Feather, and his daughter Kat. Together they use deduction and scientific reasoning to catch the criminals in these four stories.
