Book on royal family reveals rivalry between Camilla and Kate

A revealing book by author Christopher Andersen called Game of Crowns: Elizabeth, Camilla, Kate and the Throne has given us some insight into the lives of the three most powerful British royal women: the queen, Camilla, the Duchess of Cornwall, and Kate, the Duchess of Cambridge.

Although the book was released in 2016, it continues to be popular for royal fans. Vanity Fair once described it as "catnip for royal watchers."

Making a few bombshell accusations -- that the queen simply "tolerates" Camilla at this point, it's sure to be a juicy read. Shedding light on the rivalries within the royal family, the book begins in a fictional future, where Queen Elizabeth has died and Charles becomes king. He goes against his word and makes Camilla his queen, resulting in the pair becoming so unpopular that Charles is pushed to abdicate the throne to his son, William.

The rest of the book flashes back in time, exploring the real-life relationships of the three most powerful women in the family.

The two people who are cast in the most unforgiving light? Camilla, who is accused of causing William and Kate's breakup in 2007, is said to have been put off by the duo stealing the limelight as she tried to win over the British public, and Kate's mother Carole, referred to as a very ambitious woman that clamored to get her daughter to win William back.
