The Foreigner Universe series has caused the completion of my acceptance of sociological s.f., as well as my previously enjoyed types.
I won't try to analyze the books; that has already been done quite well, but I MUST recommend this series to those of you who haven't tried this category of s.f. before. You may not find it an easy read, but if you stick with it, I believe you will be well rewarded.
With the lack of a strong story on its own, the central "difficulty in communicating with an alien race" theme begins to grate a little after 5 books.
It seems kind of extreme to say it of a 464 page book, but I think it could almost have been edited down to be the first chapter of the next book in the series. When I see this kind of thing, I always wonder if the publisher is applying pressure to squeeze out that last dollar.
Explorer, the next book in the series, is out now in hardback and my expectations are very high that Ms. Cherryh gets the series back to the level of quality we have come to expect.
