I finished it; very good read and is recommended. It has a few minor inaccuracies (e.g. Gus hanging a lemon on the spacecraft, not the simulator) but is otherwise well written and interesting. I am still quite amazed how many of the astronauts were having extra-marital affairs and how this was unofficially sanctioned by the astronaut office.
Something I found curious was in the acknowledgements: many people being thanked for their help including Betty Grissom and Mark Grissom.... but no Scott. He chose not to participate?
