The Devolutionist and the Emancipatrix

In the Devolutionist, space travelers experiment with Venusian methods of telepathic space travel. They leave our solar system to discover and explore the earthlike planet Capellette of the star Capella. In the Emancipatrix, they go to the planet Sanus of the star Arcturus. In both unique worlds, they become embroiled in the struggles and challenges of the inhabitants, and much more. This is Book Two of the Dr. Kinney adventures. (Summary by A.Gramour)
