Sundiver is the best book I've read in the last 10 years.
If the premise of the book is at all interesting, I recommend trying the book.
This is my favourite book in recent memory because of the individual quality and interplay of many factors.
First, David Brin creates a very interesting story with entertaining and plausible twists.
Second, the universe David Brin creates is a complex, dense, and consistent society that is intriguing even for well read SF readers, yet this context does not supercede or overwhelm the story.
Third, Brin manages to to develop likeable (and detestable), full and rounded characters unlike almost all SF writers.
Fourth, the book effectively can be read as commentary on scientific development and cultural evolution, which is interesting in its content and expertly expressed in the detailed exposition. (I must admit I generally care nothing for this stuff, bur Brin does it so well, I became intered in it for this series. Also, this side of things only interested me after I had fully enjoyed what a great story it is with great characters in such a weird universe)
Fifth, the interplay of the above as well as Brin's creative approach give the book an overall richness and depth that is reminiscent of the best works of Tolstoy, Doestoyevsky, and Solzhenitsyn.
So far, I have only read the first three books in the series, since the books are so good that I want to space them out for as long as possible though I'm always very eager to read the next book.
I hope you enjoy these books as well. They are a very fun read.
