Journey Into Space is a fascinating, thought-provoking novel, and it has many moments of poetry and intense insight, but I'm not sure I'd recommend it as a novel, per se. In a sense, it's a great novel but not a good novel. You'll find yourself clutching your head and wondering how these people could be such morons. (The on-board inbreeding and incest that the ship's original regime failed to prevent may be partly at fault.) Science fiction readers, in particular, who are used to reading books about preternaturally smart characters may find it somewhat painful to read about such mentally challenged spacegoers.
