What for the first chapter or so seems like a serial killer novel with a twist turns out to be science fiction. I saw it coming, but I am accquainted with the genre, of course. Someone not used to it would probably be more surprised. It is also a moral story. A modern Animal Farm some reviewer has called it, and one gets a strong feeling that Faber is a vegetarian. For me as a science fiction lover the morality takes over a little, because like all true aficionados it is the Other Culture that really thrills me when I read - and I want my moral lessons to be more of a backdrop. It feels a little obvious, here. But the Other Culture is very well thought out, and not too overtly explained. And the strength of the story lies in the descriptions of the people in it, all of them. The woman, Isserley, and her quenched hopes and desires and suppressed pain, and the men she abducts, with their same feelings; not that Isserley knows. She thinks them dumb and slow, and doesn't probe further.
I love finding science fiction where I didn't expect it, and I can heartily recommend this. It is brutal and emotional while remaining detached, and despite the otherwordly slant it's one of the most realistic ideas I've come across. Recommended.
