While I am not a real big fan of science fiction, I do follow space exploration and have a soft spot in my heart for Elon Musk and SpaceX.
This was an interesting book with so many emotions. Loss, death, elation, and the determination to stay alive. It kept me turning the pages, though I felt there was some homage to the film Mission to Mars, with one of the protagonists being alone on Mars until a rescue party found him.
Mark Watney was a complex character and his determination to stay alive made it worth reading. Spend the money and read the book. You'll enjoy it tremendously.
