My first David Brin novel. I really enjoyed the premise, and Brin explores it extremely thoroughly. It mixes a very solid detective story with notions of metaphysics, personhood, consciousness, etc. 

I found the politics of the book to be quite dated (published 2002). It’s full of a certain kind of neoliberal optimism that I found frustrating.

Otherwise, I really enjoyed this one! Pretty breezy read. I liked the puns sprinkled generously throughout, but I may be in the minority here.
