In the beginning of this book, various professional and amateur astronomers notice that Mars is changing color. It is becoming slowly less red and more grey. Eventually, they figure out that it is being consumed by Von Neumann machines. For those who aren’t familiar, these are machines capable of replicating themselves. A team of Very Smart People in Huntsville, Alabama ends up developing the concepts for and leading the defense. If the location sounds familiar, it is the site of the Marshall Space Flight Center and the Redstone Arsenal, some of the premier rocket design locations in the United States. The book starts fast, and gets faster, as a reconnaissance probe is sent to find out more about the Von Neumann “probes” and then these attack Earth. The “motivation” of the probes is interesting. They only kill as a side effect. Mostly they just grab anything metal, including dental braces, cars, metal eyelets out of shoes, dog tags and rebar out of buildings, to make more of themselves. The story focuses on the Very Smart People, and they are quite a fun bunch of rocket scientists.
This is what happens when you combine Ringo, known for fast moving prose and a twisted sense of humor, with Taylor, who can write one heck of a fast moving plot. Hold on tight! Just like in his other works, Taylor’s story creeps up on you. It starts very small and by the end the fate of the world is at stake and the action scenes crowd each other out on the page. The initial alien attack conveniently lands near Paris. I say conveniently because the US can act as the Last Citadel. I suspect it also gave our authors a chance to destroy France. This book is great fun, the science is fascinating and the main characters sound like a group of people I’d like to have a beer with.
