There are three threads to Recursion, all being explorations of several connected and multi-layered psyches at various points in the future. First there is Herb Kirkham, a 23rd century man whose self-replicating Von Neumann Machines have devoured an entire planet. He thinks he's escaped the clutches of the all-powerful Environment Agency until a dapper man by the name of Robert Johnston enters his life, and his spacecraft, and enlists him to clean up a much bigger mess out in space called the Enemy Domain. Then there is Eva Rye, a solitary 21st century woman living in Wales who hears the voice of the Watcher in her head and eventually tries to kill herself. She fails, of course, but why is the Watcher talking to her? Lastly we have Constantine, a mysterious 22nd century employee of the nano-tech company DIANA. He also hears voices but that's because he spends a great deal of time in the Australian virtual reality city of Stonebreak, so much so that he becomes increasingly unsure if he is not a virtual reality construct himself. He learns there are far reaching consequences to his job that not only lead to the emergence and proliferation of a sentient nano-technology, but consequences that also reach back in time to a young and disturbed 21st century woman.
Cutting back and forth in time from nearer to further future, this is a clever Singularity story about before, during and after the event itself though I noticed that Ballantyne, strangely, never once uses the word 'singularity' in the entire tale. I wonder about the reason for this, and other factors such as Eva’s over-long scenes set amongst other young maladjusted people in a care home and their subsequent escapade, lead me to speculate that is more identifiably a young adult novel but one curiously aimed at grown-ups. Recursion also has something of an identity crisis, a kind of multiple personality that finds recursive echoes in the story itself: disembodied voices, hidden identities, a confusion of worlds both real and virtual. The three threads all appear so markedly and deliberately different in voice and style that they seem barely related other than by the over-arching plot that connects them, though each thread’s effect on the other two threads does cleverly give us the ‘recursion’ of the book’s title. Ballantyne has made a quirky, though not brilliant, debut; there may be things lacking here that further books, if this is the first of a series, will hopefully provide.
