I work for a publisher and not as a bookseller, the current way of giving feedback is not linked to the titles themselves, but stocking them. In the past it was easier to actually give feedback on the book itself without the first set being a must. So here it is:
Andy Weir's book was an engaging read, the right kind of travel literature for a sci-fi nerd on a long journey. It kept me engaged and entertained.

I read this book while I was on a skiing holiday. As I dragged my ski clothes and especially ski boots on every morning I was thinking of Mark having to put all his kit on just to survive.
I really enjoyed this story. The claustrophobia and loneliness of being the only person on a planet really came through.
