Six millions years previously, Abigail Gentian, scion of an influential and rich family, made one thousand clones of herself and infused each one with her personality and memories. Since then “Gentian Line” has travelled the Milky Way at sublight speeds, exploring, experiencing and helping civilisations. Every two hundred thousand years, the “shatterlings” of Gentian Line come together in a grand reunion, to share experiences and memories, and to remember their lost.
Purslane and Campion are two shatterlings who, despite strong taboos against it, have fallen in love and travel together. They are thousands of years late for the coming reunion. Once they arrive, they find that the Line has been attacked for unknown reasons, and decimated.
The premise is interesting, tackling the tricky concept of deep time and societal survival. Is it possible for a planet-bound civilisation, or even an interstellar empire, to sustain its own existence beyond a few tens of thousands of years? And what of consciousness, machine or biological. How can these handle intervals of millions of years, even if many are spent in suspended animation?
Unfortunately, too much of the story depends on reactions to events that happened previously, which are revealed piecemeal in massive and awkward infodumps. The plot will grind to a halt as a character expounds for pages and pages on events of five millions years ago and how they explain the events of last year in perceived time (which perhaps actually happened fifty thousand years ago in actual time). The love story of Purslane and Campion is sweet and tragic and compelling, and that would have made a lovely book. However, the whole edifice is heavily weighed down by having to explain and analyse the effects of deep time and ancient history, making it an ungainly slog only rescued by Mr. Reynolds’s superb prose and flair for illustrating the immense. Ironically, the final chapters are absolutely beautiful and would have been an amazing coda to a less ponderous narrative.
