Very interesting read and great for discussion as so much is relevant to all of us about goals and success or failure in life

i enjoyed the book and it is on the \\\"dark\\\" side; however, I enjoy both movies and books that are dark. I loved Gone Girl and I probably will read all that Gillian Flynn writes as I like her style and surprises.

Difficult read unless you are interested in the technical aspects of space travel. Enjoyed part of the story but really skimmed so much of the book as not interested in Science Fiction literature.
