The Big Jump (Vintage Ace SF, G-683)

Dangerous hyperspace journey. A family-held corporation has tested interstellar space travel to Barnard's Star - and something has gone badly wrong. They race madly to put a second mission together before the oversight people can shut them down, as an outsider becomes involved with one of the women in the family, and mixed up in their corporate intrigue going along for the ride. A really very short novel, with a reasonably powerful ending. 3.5 out of 5
