Treachery In Outer Space

Carey Rockwell's Tom Corbett books are earnest, optimistic mid-century adventure fiction at its most enjoyable — a space race to Titan, a mining conspiracy, and three cadets with genuine camaraderie all add up to a plot that moves. The science is charmingly pre-Voyager, the characters are broad rather than deep, and it wears its 1954 sensibilities plainly, but for readers who enjoy classic science fiction or nostalgic adventure series, this delivers. The fact that it's freely available through Project Gutenberg makes it an easy recommendation.
