The Planet Mappers dates from 1955 and was the last novel of E. Everett Evans, published during his lifetime (1893-1958). Two teenagers, Jon and Jak Carver, are out to help their famous explorer father, Tad, locate and chart new worlds in distant solar systems, and denote ones especially suited for human colonization. Can the boys manage to survey an entire solar system of planets without assistance from anyone else, following the exacting rules laid out by "The Board" which regulates and certifics such discoveries? And when is the evil Slik Bogin going to show up with his armed space ship and crew of cutthroats and steal their discoveries?
