George, Nicholas and Wilhelm: Three Royal Cousins and the Road to World War I by Miranda Carter

This book offers stunning insight into the lives of two of the 20th century's most powerful monarchs...and the King of England! Detailing the shockingly poor education all three royals received, their unimaginably opulent (and lonely) lifestyles, and the juicy details of their psychological hangups, Miranda Carter's work paints an engaging picture not just of the roles these men played in history but also of the world they lived in. Bottom line: If you want to know how kings and emperors lived in the twilight years of empire, this is the book for you.
