Firefall
Blindsight is a hard sci-fi novel about first contact with aliens in the near future. A crew of four transhumans and a vampire are sent on a spaceship to investigate an anomaly in the solar system after a swarm of alien probes scan Earth.
The Colonel is a short story that serves as a bridge between Blindsight and Echopraxia. It follows Colonel Keaton—the father of Siri Keaton—as he investigates whether the Bicameral hivemind poses a threat to baseline humans.
Echopraxia is the second book in Peter Watts’s Firefall series, although it takes place roughly at the same time as Blindsight. It follows parasitologist Daniel Brüks as he gets dragged into a conflict between multiple transhuman factions, travels to the Icarus station orbiting the sun, and back to Earth.
