i know few writers who can match tepper's world building and social imagination, and none who are as capable of envisioning a future that isn't exactly like the present without succumbing to to the usual post-apocaliptic nonsense.as other reviewers have noted, this novel contains a lot of tepper's familiar themes. which is not a bad thing. i found _the cmpanions_ much more readable than _the visitor_, which i still haven't been able to finish, but not as much sheer fun as, say, _the family tree_ or_fresco_.still, not quite topnotch tepper is still much better than most of the rest of the stuff being published. her writing is superb, her imagination is beyond description, her characters are clearly drawn and realistic. some of her solutions to social problems are inspired (and occasionally hysterically funny), and don't i wish they were possible. i can't imagine a reader whose mind wouldn't be stretched by reading her.and the process would be thoroughly enjoyable.
