1768. Charlotte arrives in Naples to marry a man she has never met. Two years later, her sister Antoine is sent to France to marry another stranger. In the mirrored corridors of Versailles, they rename her Marie Antoinette.

But the sisters are not powerless. When they were only children, Charlotte and Antoine discovered a book of spells – spells that seem to work, with dark and unpredictable consequences.

In a world of vicious court politics, of discovery and dizzying change, Charlotte and Antoine use their secret skills to redefine their lives, becoming the most influential women of the age.
