I vaguely remember that book as being a fascinating idea that somehow ended up as a rather annoyingly dull or awkward story. It's definitely a book that I only vaguely remember - which my husband is now telling me over my shoulder was very good - and, after some dialogue, he's conceeded was "yeah, some plot with human stuff, but really cool science! Now I feel like a geek." That's only 'cause you are, hon. :)
