The Future of Another Timeline

There were some really cool things in this book... I really liked the concept of the machines and using geology. As good sci-fi does, it also was a startling look at our culture from a perspective that shows just how fragile some of the things we take for granted can be. I listened to the audio book for this on Audible and I did not care for the narrator (Laura Nichol), but the addition of music in the audio book was awesome.
