I find myself astonished at the amount of criticism Harry's book has engendered considering it is yet to actually be published! The false flags are stunning; yes Prince Philip walked behind his Aunt and her family's cortege however, times were different and he knew it was expected which, considering he was 16 years of age, is hardly surprising. Harry was just 12 years of age and not yet even classed as an adolescent when he walked behind his mother's coffin.
All the conversations about Zara, Eugenie etc. being second children is totally irrelevant. Harry, as his uncle Andrew before him was the Spare to the Heir to the throne. As such he inhabited the same world as William in the knowledge that he was destined for absolutely nothing except being his brother's spare and that would not change until such time as his brother married and produced his own heir and preferably spare as well.
As a spare Harry was never encouraged to have any aspirations other than being his brother's stopgap and, on occasion, scapegoat. He was in no way educated or prepared to "earn his own way" than those before him and if we look back just a little we can see how Prince Edward, originally fourth in line to the throne, was hounded by the media.
Sophie had her own moderately successful design career but the moment she and Edward married they were accused of using the BRF to make their fortune. They were both hounded unmercifully until the sad little announcement that they had both decided to forgo their careers and join the family firm like the firm actually needed two more full-time workers at that time.
So here we wait for Harry's biography to be published. We know what he said it would be, i.e. his truth and his feelings growing up to be the man he is today. I am holding out for the book since it will be the first personal account of a Spare. How the world, the country, and his family treated him, and how he felt about it. It will also possibly show what advice and support he got from his family to try to create his own niche.
With all the "leaks" from all the usual suspects, I can only surmise that there are more than a few people who feel threatened by Him and what he may say about them, both family members and courtiers, and the pre-emptive character assassination seems to support that.
