In this book, royal expert Robert Lacey traces the divide between Princes William and Harry from their early upbringing within the British monarchy to the present day.

Princes William and Harry were both raised as royals, but only one of them would be king.

They bonded closely after their mother's tragic death amid tumultuous scandals that followed the family.

The brothers have chosen distinct paths in life - one upholding tradition, the other breaking with convention.

While the severing of their once-close relationship has been gradual, Prince Harry and his wife Meghan's decision to depart the royal family is said to have driven the final wedge between him and his brother, William.

Robert Lacey is a British historian and expert on the royal family, having served as historical consultant on the award-winning Netflix series The Crown.

In Battle of Brothers: William, Harry and the Inside Story of a Family in Tumult, Lacey provides a fascinating and intimate portrait of two intertwined yet distinct lives within the family that continues to reign over Britain, the Commonwealth nations, and the tabloids.
