The world is suffering with climate change. A group of entrepreneurs decide to undertake a risky mining venture on an asteroid. When things go wrong three of the astronauts escape to Earth leaving two of their comrades behind. This book centers on how the three make substantial engineering strides to build equipment to return to the asteroid.
The tension is not only working against time to accomplish the rescue mission, but international tensions are created by devastating climate change. In the circumstances, the government doesn’t want to back the rescue mission, so the three crew members are on their own.
The opening chapters are rather slow focusing on the lives of the main characters. They are reasonably well drawn. I found James the most interesting. He is the driving force behind accomplishing the rescue. Once the author gets into the technical details of preparing for the mission, the book gets more interesting. However, the science can be heavy. I enjoyed it, but it can be overwhelming if you only dabble in technical matters.
This is the second book in the series. The first book Delta-V does not have to be read first, but it can be helpful from the standpoint of getting into the technology. If you enjoy sci-fi with plenty of technical detail, this is a book you should check out.
I received this book from Dutton for this review.
