My second try at Mr. Ben Bova's style of sci-fi after a much hated experience of reading voyagers. I liked this book.Realistic depiction of a refugee's fear - safety of their women. I liked that sensitive touch to the story. Dorn got a little irritating in the end with his anti-violence sermon in the face of imminent death but I guess that's the deliberate handiwork of the author. 'The artifact' was a little loose sub-plot but brilliant character development saved any further trouble with that minor setback.Not a good book, definitely not a bad one and not mediocre either. It lingers in the deep black space like the story is set in.
