I find many omissions and typos in these summaries. There seems to be a bit of a bias toward Trump. Mary absolutely has every right not to disclose anything about her daughter. That is private. The recommended books in the end all seem to lean toward great leaders being mentally ill. Malignant Narcisstic Personality Disorder makes for dangerous leaders like Emperor Nero and Adolf Hitler. I believe Mary, and want to know more about her uncle's behavior, which definitely does not come as a surprise.
I loved this book, and I love the author as well. An inside look from a well-educated psychologist, and a monumental psychological case study, D-Trump. Enjoy, it is a wild ride.
