Do not waste your money. Most boring book I have ever read. Over half the book is about Charles and Diana. Oncw we eventually get to the title characters it becomes a justification of Harry and Meghan. William is to blame for all Harry's bad headlines such as Harry in a Nazi uniform,
There is nothing new in the book just a rehashing of old stories. If you are an insomniac it will help you sleep.
A better balanced read is the Lady Colin Campbell book which is fair to all sides. Here it is pointed out that Diana wanted the boys to be treated the same and spoilt Harry. She did him no favours he was unpopular at school (not William's fault), he was "helped" with academic work etc etc. The last SPARE is an arrogant ne'er do well and look what's happened there.
