After the extinction of humans, how do you define humanity?Since the Introdus in the twenty-first century, humanity has reconfigured itself drastically. Most chose immortality, joining the polises to become conscious software. Others opted for gleisners: disposable, renewable robotic bodies that remain in contact with the physical world of force and friction. Many of these have left the solar system forever in fusion-drive starships.And there are the holdou...

Cass has stumbled on something that might be an entirely different type of physics, and she's travelled three hundred and fifty light-years to Mimosa Station, a remote experimental facility, to test her theory. The novo-vacuum she creates is predicted to begin decaying the instant it's created, but even so short-lived a microscopic speck could shed new light on the origins of the universe.But instead of decaying, Cass's novo-vacuum is wildly successful and begins expanding, slowly ...
