I consider David Brin one of the three best genre writers among those who started writing after 1970 (the other two are Lawrence Watt-Evans and Steven Brust; Barry Longyear might be on that list except I think he started writing before 1970, and I haven't seen anything new from him in quite a while. Barry Hughart would be on that list if he hadn't had to give up writing due to his idiotic publishers).I'm a huge fan of a lot of his work. His original Uplift trilogy is a favorite of mine. But I was disappointed by the first two books in his second Uplift trilogy. Heaven's Reach represents a significant improvement on those books.It might get a bit too cosmic (in the same way that his Kiln People did, towards the end), but it's a solid, intelligent, imaginative, and well-written book. Perhaps I like it more because the action takes place out on the space lanes, rather than being cooped up on the sooner planet of Jijo.Many mysteries are explained, and the resolution, while by no means tying up all the threads of the Uplift series, is quite satisfying. I plan to go back to the first two books in the trilogy to see if I like them better in the light of this book.And I'll be re-reading the entire first trilogy before too long, of course.
