It sounds like a really profound read, but (now deceased) Martin Booth’s story of a Russian Cosmonaut abandoned in the MIR spacestation is really quite straightforward. Captivating for it’s description of the minutiae of day-to-day spacecraft life contrasted against coarse outdoors and hunting stories from his rustic past and early military training, a Cosmonaut contemplates his fate. 
The purity of space is set against mankind’s fouling of the atmosphere. The irony of this is not lost on our space traveller when the vessel’s equipment starts to falter courtesy of some U.S space-junk and malfunctioning human waste filters. It was a very pleasant and refreshing read; the sort of thing you could pick up and read a chapter or two and the then drop it for days (like I did). The writing was crisp and precise, much like the disciplined life aboard the craft. I give it 4 stars.
