Oh, I finished this book a few weeks ago! I really enjoyed it. I loved how it focused on Walt’s personal life, as well as his work life. It really gave a lot of information as to who he was as a person - not just what he accomplished and how he did it.
My only complaint was that Sharon’s adoption was completely skimmed over - almost as if it didn’t happen. It was mentioned in the introduction of the book, but when Walt’s life was being reviewed chronologically, it just said “They had a second daughter, Sharon.”
