Echopraxia (novel)
Echopraxia is a hard science fiction novel by Canadian writer Peter Watts. It is a "sidequel" to his 2006 novel Blindsight. It follows the story of a biologist who gets caught up in a voyage into the heart of the Solar System among members of a transcendentalist monastic order and allies to investigate a mysterious signal seemingly coming from the mission sent to initiate first contact in Watts' previous novel.
The title refers to a psychological condition in which a person involuntarily mimics actions they observe.
