Just finished reading this book and found it very interesting. It is packed with facts about the king that Thai people just don't speak about, (i.e. the fact that he lost an eye in a car crash in France when he was a young man) The author was given exclusive access to the king and spent periods alone with him over a period of years. The book also delves into the Thai royal family lineage and describes how his mother rose from poverty and selling fruit on the river to marrying his father prince Mahidol who she met in America.
It covers his life from a young boy with a western education and mindset who is thrust into the strange ceremonious world of the Thai royal court, firstly as brother to the previous king Ananda and then later as king himself after Ananda is killed under mysterious circumstances. It tells the story of the intrigue surrounding the royal court and how the king set about reforming the country from behind the scenes despite the political difficulties and interference form the superpowers who regarded Thailand to be strategically well placed in the battle against communism and the domino effect.
I also read that the King actually won a medal (gold I think) in the 1967 South East Asian games for windsurfing and not an Olympic Bronze as stated in the quiz on this forum last year see here . I demand a recount.
Reading this book will give you a better understanding of the Thai monarchy and why the Thai people love and respect their king so much, I certainly have more respect for him after reading it. Well worth a read.
