Intriguingly Factual Reads on the Hot- and Blue-Blooded

These are not your high school history teacher's textbooks.

Sex with the Queen: 900 Years of Vile Kings, Virile Lovers, and Passionate Politics, and its male consort Sex with Kings: 500 Years of Adultery, Power, Rivalry, and Revenge, are both written by a namesake descendant of Eleanor of Aquitaine, Eleanor Herman.

In these two luscious books, Herman outlines the auspicious--and more often ominous--adulteries of European royalty, from the middle ages up until the modern Prince Charles and Princess Diana.

As you might expect, they cover many subjects not often touched by history teachers. But, probably for that reason, they are entertaining while still being factually correct. Perhaps a guilty pleasure to read, you will nevertheless be assured that they are not simply fabricated for your enjoyment.

The two books offer intriguing insight into the act of adultery among nobility--its origins and outcomes--with a pinch of feminism and a heaping spoonful of wit. Herman explains not only political and social risings among the mistresses and lovers of kings and queens, but also the fashions and foods inspired by them. They cover nearly all of Europe, from Britain and France to the cold reaches of Russia, and they span from five to nine decades.

She also offers a book on a papal puppetry by a woman, called Mistress Of The Vatican: the True Story of Olimpia Maidalchini, the Secret Female Pope, which Publisher's Weekly called "a window into an age of empire, nepotism and intrigue that rivals any novel for fascinating reading."

If you're looking for a painstakingly-researched read that delves into social and political history, but don't want to be reading yourself to sleep, take a look at these.
