The Royal Family should be nervous about Prince Harry's new memoir: inside

Multiple sources report that Prince Harry's upcoming memoir will cause the royal family plenty of headaches. 

Page Six can exclusively reveal new truth bombs in the Duke of Sussex' $20 million book.

One NY publishing source told us: It's juicy, 

that's for sure, and despite reports it has been pushed back.

"Harry has never mentioned his childhood in the past, and there is some content in it about his past," another publishing insider added: 

His family should be nervous about what's going on there."His family The situation there should make you nervous."

However, Harry has gone out of his way not to mention anything negative about his grandmother Queen Elizabeth, as Page Six previously revealed.
