I've read the whole book now and there are some snippets of extra information but for me, there are no huge, new revelations about anything although there are several instances of press reports being challenged with an alternative narrative.
The detail of some personal events could only have come from extremely close friends and I wonder if this will come back and bite them. If the friends co-operated with the authors then in effect, that's Harry and Meghan co-operating with them or endorsing the book.
Overall, for me the book confirms:
1 My belief that some of the UK media published false, defamatory stories about H & M, which quickly became global ‘truths’ .
2 Those points I’ve posted here previously about Harry’s apparent inability to accept that his position means his father and brother’s work must always take precedence. Harry and Meghan’s plans and work must always fit around Charles and William. BP and KP will inevitably seek to ensure that H&M’s coverage and popularity don’t eclipse William. It might be a tough pill to swallow but the public will consider the immense privilege of Harry’s life to be a more than adequate compensation.
3 Another point I’ve previously made, which is that Harry was/is the least equipped guide and mentor to Meghan becoming a working royal because his judgement is so skewed by resentment and his (at times) fragile mental health.
4 The other things I’ve said about the whole set up of separate households being dysfunctional and unfit for purpose because it fuels competition, tribal behaviour, conspiracies and secret briefings. The system seems rigid, archaic and often ineffective. I wonder if much has changed since Diana’s complaints about the ‘men in suits’.
5 That Meghan is an admirable person with huge potential but she was launched into public life far too quickly, given that she was always going to be pilloried in the press (as Camilla and Kate were). The changes in her life circumstances were significant, numerous and within a short timescale so no wonder she became emotionally exhausted with the negative (and often false) press.
6 That their departure is an upsetting and sad situation that needn’t have happened if Harry hadn’t been so volatile, impulsive and impatient.
Looking to the future, I don’t know if those who have been criticised can progress past that (eg if I were Catherine I’d be fuming). My sincere hopes are that Harry and Meghan can make a success of their new life but I still think they’d have had a much better chance of doing that here if they’d slowed their pace and dimmed their lights rather than “hitting the ground running”.
