this 23-pages short story sets before the asteroid-spaceship "Eriophora" ships out for a one-way ride to the end of time.
If you (plan to) read "The Freeze Frame Revolution" + "The Island", you may want to read also this, as it gives some minimal background about the mission and about Sunday Ahzmundin's past, filling some lacking details in the others stories of the "Sunflower cycle" - you know, Peter Watts rarely presents the reader with all the details, instead he let her/him discover them her/himself - when possible.
The (absence/irrelevance) of Free Will is a central theme, and Watts exposed this through in his unique "blitzkrieg" writing style which concentrates high-end concepts in sharp sarcastic, merciless and bleak bullets that punch you in the face: "[...] you never know how an automaton will react to autonomy". Chapeau.
This being said, I found the writing too solipsistic: details never spelled out but taken for granted and the abuse of technical jargon makes reading not always easy nor pleasant. Sometimes looks like Watts was writing this story for no other audience than himself, which is a real shame, him being one of the most brilliant and original authors of hard SF currently at work.
