I have not read Echopraxis yet, but I thoroughly enjoyed Blindsight. Some very thought-provoking concepts in that book.

The idea that vampires needed to take “anti-Euclideans” and the way the ship was constructed to avoid generating right angles were some great details.

Just a heads up, don't go in to Echopraxia expecting it to feel like Blindsight. When I first read it, I was actually pretty disappointed overall, and a few of my friends had similar reactions.

Over a couple of years a few re-reads, though, I've come to enjoy it perhaps even more that Blindsight, but in a completely different way. It fills out a lot of the posits opened in the first novel, without coming to specific conclusions, but it gives you a lot to think about.

It's the world builder, odd that it comes second but if it had come first then most people would have been put off! I liked that the main character was the least super empowered of any of the characters though.

Echopraxia is great. I never understood those who thought it was disappointing. Blindsight is wonderful, but Echopraxia is possibly the more inventive one. It certainly pulls the narrative in a different direction.

I also really, really recommend The Freeze-Frame Revolution. It's about the crew on an starship trying to stop the rogue (sort of) AI that runs everything, the twist being that the crew is constantly under surveillance and must periodically hibernate in shifts for months or years at a time. It's a novella plus a handful of short stories set before and after the novel (all available for free on Peter Watts' website). Be warned, it's one bleak, dark universe.

Also, don't miss out on "The Colonel" (also on his website), a standalone short story that also happens to be a direct sequel to Blindsight.
