Philip Eades book is quite good. The "Turbulent Early Life" refers to his upbringing as an exiled prince not to anything especially racy he might have done as a young man. While not an official authorized biography it was done with cooperation from Philips equerry. and the palace arranged for the author to have access/interviews with Philips friends and relatives as well as the Royal Archives, and the Hesse State Archives. It is in no way some sort of trashy Kitty Kelly tell all type of book and is well worth a read.
