Admittedly I'm late to this, but it might be the best sci-fi novel I've read for a few years.
Hard sc-fi about first contact, transhumans, religion, identity, AI...it even has a vampire!
Peter Watts doesn't dumb down, it's an elevated experience that sometimes takes a little effort to keep up.
Which I found to be the perfect antidote to some of the latest Hollywood offerings in recent years, that seem to value exposition and expensive CGI over creative and believable storytelling.
A brilliant novel!
