This novel was first published in 1948 so many things are very dated, especially since it was written for adolescent boys. You have to ignore the dumb-blonde characters of the girl and the mother. Also, the smoking on board a spaceship. However, the story is still a good one, a coming of age in an age of space.
I do really like the Full Cast Audio version. The many different voices give a good idea of the story. Space cadet
