    Doomsday Holdover

    At three in the morning, network engineer Maren Kellner finds nothing wrong: every screen reads green. But the clocks that keep a mobile network in step have begun to drift apart, and nobody above her wants to hear it. A techno-thriller with no cavalry coming.

    E-book · Paperback

  2. Book 2

    Doomsday Sequence

    On a stock exchange, the system that ranks orders by arrival time still swears it is healthy, while one trader’s fills come back in a sequence that makes no sense. The engineer who owns it and a surveillance analyst work the same logs from opposite ends.

    E-book · Paperback

  3. Book 3

    Doomsday Epoch

    On a regional rail line, one section keeps turning itself to red and stopping trains, and nothing on the panel explains why. Every instrument points at the signaller who holds the seal. A stopped train is the safe result; the danger is whoever overrides it.

About Sebastian Sterling

Sebastian Sterling writes thrillers that begin where the paperwork does. A soil sample that reads wrong. A payment that clears too smoothly. A coffin that weighs the wrong amount. A file with a name in it that should have been dead for thirty years.
