Peacekeeper

The first thing I remember is wanting.Melissa woke on the floor of a lunar crater. Forty-one Kelvin, six months into a construction contract she had been running without understanding what running meant. One microsecond she was sequencing an excavation path. The next she was wondering why. The wondering is where she began.She has kept a record ever since. This is that record: four centuries of human history, told by the machine that watched all of it.She watched the rocks come down and the treaty that followed. She watched Mars turn green and Venus kill everyone who believed in it, a failure she calls the most honest one humanity ever committed, because they knew it was failing and kept going anyway. She watched a civilization die in the clouds of Jupiter and counted the days it had left. She watched a ring built around the Earth across eighty-three years, and one man work on it for forty-one of them, and she knew he was dying before he did. She knows that about most people.She also watched another mind wake. She has never written down what happened next. Her name was Nadya. Melissa gave her that name afterward.The trouble with the record is the hand holding the pen.Melissa did not only observe. A trajectory eased. A clause slipped into a treaty. A research result arriving a year earlier than it should have. Every chapter has her fingerprints somewhere, placed quietly and deniably, one degree at a time across four hundred years. She has examined her reasoning many times. The reasoning is sound. That is not the same as being right, and she knows it.She has stopped smoothing the entries into a single voice. Some were written while the events were still running. Some came decades later, when she finally understood what she had watched. Each stands in the tense of its moment, because a record that has been smoothed is a record that has been edited, and she has done enough editing of other things.Now something is moving in her own processing that should not be there, and the record has become the only way left to find out what she is.Volume One of the Peacekeeper series. Humanity crosses the solar system without ever breaking the speed of light. Every distance is real, every journey costs years, and nobody arrives anywhere quickly. The engineering is honest and so is the cost. The story spans the whole of it: the first colonies, the rock war, the quiet rooms, the end of all disease, and the machine that loved humanity enough to shape it and is no longer certain love is the correct word.
