I went into this with high expectations having loved 'The Martian'. I wasn't disappointed. The grounded technical knowledge followed the same path 'The Martian' did by providing a believable basis for the storyline. The concepts were entirely engaging and I loved the journey. I could not recommend 'The Martian' enough and this one falls into the same category. If you haven't come across Andy Weir I recommend you pick this one up either along with 'The Martian' or on its own. They are 2 completely separate novels and individual stories but it is very apparent the writing style comes from the same Author and it is a style I find myself immersed in and thoroughly enjoying. Keep up the great stories Andy. I look forward to the next leap in another different direction again!
