Includes the short story The view from the end of the world.

Clair's world has changed beyond recognition. The d-mat network is broken and matter transportation is unstable. People are trapped, injured, dying, with no way of reaching them. Clair - 'the girl who killed d-mat' - is enlisted to track down her missing friend Q, the rogue AI who repeatedly saved Clair's life and who is the key to fixing the system. But does Q want to be found, and can she be trusted? Targeted by dupes, abandoned by her friends, caught in a web of lies that strike at the very essence of who she is, Clair finds powerful allies in RADICAL, secretive activists who are the polar opposite of anti-d-mat terrorist group WHOLE. But Clair must tread carefully to avoid trapping Q in a life of servitude - or worse, sending her to an early death by erasure. Caught between pro- and anti-d-mat philosophies, in a world on the brink of all-out war, Clair must decide where she stands - and who she stands with, at the end.
