It's hard to review this book without giving anything away.
We follow 2 timelines. (This is not a time travel book.)
In the future, there's an evil genocidal synthetic (robot) out to purge the world of pesky humans.
Meanwhile in August of 2017 in Austin, TX, we follow a Youtube blogger, a Brinks driver, and a tech worker living their lives. Something doesn't seem right about their world, and I don't just mean Youtube commenters.
Well written, and the Austinites are good relatable characters.
The book stands on its own. This is most closely tied to Perion Synthetics and to a lesser degree the other Vinestead novels, but you don't have to have read any of those previous Verastiqui/Vinestead works (including Perion Synthetics) to understand or enjoy this book.
No sex in this one, but lots and lots of violence in the future.
