Floating through our galaxy is Hayford Peirce's Black Hole Planet. It orbits a tiny collapsed star that feeds on matter from the Oort Cloud. Only three or four centimeters in diameter, the black hole radiates sufficient energy for the subsistence of two intelligent races on its single earthlike satellite. The black hole planet is an imaginative creation, and Peirce's adventure plot moves along briskly. — Tim Sullivan
