When a war engulfs Earth, the astronauts on the space station are left to fend for themselves. Eighteen years later, the space program begins again and makes contact with a survivor on the station.
This book reminded me of the Martian, especially the portions about being alone and then being able to talk with others. A lot of the initial emotions described here are obviously the same. Later this book diverges, adding a romantic element to the story.
Like the Martian, this book has lengthy descriptions of the science of space travel, but is not as math intensive. It tends to explain the problems conceptually, eg. air drag slows down the station. We get to know a lot of the problems that need to be solved to keep the station operational.
The characters are well drawn, the girl on the station is very sympathetic. I have a little trouble accepting that the background that she was able to do everything needed on the station for years by herself, but once the story begins, her skill level seems realistic.
The plot begins slowly, with a good amount of space given to explaining the background. It picks up later in the book, as obstacle after obstacle crops up to her descent to Earth. It ends with a clear setup for the next book in the series, which will deal with the political complications of the situation.
