Existence by David Brin
My rating: 3.5 of 5 stars
I give this tour-de-force exploration of one possible answer to the Fermi paradox a 3.5. Better than a three, but not as good as a four. However, there is no 3.5, so four it is. It reminds me, in structure, of Kim Stanley Robinson’s 2312–a long, meandering novel with multiple characters and story lines, where the plot eeks along at a snail’s pace while entire chapters are turned over to philosophical musings.
Then, in the last quarter of the book, the myopic detail of the story lines is dumped to take a different point of attack on resolving the larger story, leaving the emotional payoff of the original story lines hanging, to be resolved by various, off the cuff “tellings,” rather than “showings.” This is frustrating, although you do find out what happened to the characters, and the ultimate message of the novel is positive.
