I found the book to be well worth reading for one main reason. It was the story of Harry, how he saw his childhood, his youth, and young adult all the way to veteran. How he saw his world. It is not an exact science but the recollections of a child, youth, young adult and now Harry the adult.
As expected, it raised a lot of ire and most of what he was accused of writing prior to the book's release actually did not appear in the book at all. Did anyone admit they got something wrong? Of course they didn't. But I found it staggering that Harry should have personally felt used and abused by the family that he admits he still loves.
How can someone be in such pain in your close little world, and nobody even notice. Rightly or wrongly, Harry is still under the impression that he was even there for spare parts (horrifyingly gross as that sounds, people have had another child for exactly that reason). But it speaks to how he values himself and I believe Charles is probably more hurt by his inability to get through to Harry that he had and still has, value and he is loved.
Charles probably didn't like him very much when the book was published. Let's face it, the gossips and royal reporters were all initially pontificating that Harry would never write a book, was not intelligent enough, didn't have it in him to pull it off. IMHO Charles has passed the initial outrage caused by all the "in the royal know" tripe, read the book and wondered how they had all missed that Harry had a serious problem. Worse, that lack of self-esteem made him ripe for the picking. That is the only way I can understand him reaching out to him for the Coronation and his sadness that he he didn't stay a few days or bring his kids. (I am noting his birthday toast to Archie "wherever you are".
