The beginning of the book was a bit wordy in mathematical theory. It did make the point that scientific people often see the world in their own way. I enjoyed the premise of the book. It is enough to be away for months and try to return home, one cannot imagine literally being in space for a few months. Keith returns to earth finding his world completely gone. I enjoyed the way that he tries to re-think his world and also his new friend, often we find friends when/where we least expect. Due to my moniker, I feel I need to give a heads up, there are a couple of rather graphic scenes, they are not gratuitous, but needed to tell the story.
