Star Splitter is a stellar near future science fiction novel that is more speculative than fantastical, making it perfect for readers that enjoy books that portray a plausible future. In this story, Jessica Mathers is summoned to deep space by her parents to be a research assistant, when she'd much rather just stay on Earth. In this near future, people are scanned and essentially 3D printed at their destination, to get around the difficulties of deep space travel. Quickly this shows itself to be a problem, because Jessica has been printed twice - and the first printed Jessica knows things that the second printed Jessica doesn't. First printed Jessica arrives on the Thesus, the ship orbiting the planet she and her parents are supposed to be living on for the next year. But when Jessica's parents arrive, things start going haywire on the ship. Alternately, second Jessica arrives after the ship has crash landed on the planet itself only to find herself (and herself) as the only survivor. But there's things that the first Jessica isn't telling the second Jessica, and our newest iteration is determined to figure out what that is. Normally, these type of books go heavy on the world building details, and lighter on character development. This isn't the really the case here, and I kind of wish the book had been longer and that Kirby had fleshed it out with those details more, because the concept is both interesting and a sobering reminder that any technological route we go, whether to explore the worlds beyond Earth or the ones here has consequences. Kirby creates a subtle sense of terror and paranoia, one driven around making contact and surviving more so than terrifying aliens or deadly living conditions. This was an enjoyable and thought-provoking read that had me wishing for more. A complimentary copy of this book was provided by the publisher. All thoughts and opinions are my own.
