Heaven's Reach

Even better on a re-read. I picked up lots of detail that I either had forgotten or hadn't noticed on the first read. David Brin really let his imagination run loose. Earthclan triumphant against incredible odds! (With quite a lot of help from some seriously advanced entities.)
Solid 4 stars.

Note: This trilogy is all one story. Start with the first book.

Spoiler for an earlier book: I do wish David Brin would return to the planet Kithrup ([b:Startide Rising|234501|Startide Rising (The Uplift Saga, #2)|David Brin|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1476445711l/234501._SY75_.jpg|251634]) and tell us the fate of those who remained behind (Tom Orley, Charles Dart, and the others).
