"The Serpent Queen" is a cunning account of one of the most influential women ever to wear a crown: Catherine de' Medici; considered an immigrant, common and plain, de' Medici marries into the 16th century French court as an orphanedteenager, expected to bring a fortune in dowry and produce many heirs; she quickly discovers that her husband is in love with an older woman, her dowry is unpaid, and she is unable to conceive; yet, with only her intelligence and determination, she manages to keep her marriage alive and masters the bloodsport that is the monarchy better than anyone else, ruling France for 50 years.

Catherine aims to unite France under King Charles IX, pushing her agenda of a secular state; the Bourbons present an ambitious trade deal with Protestant England; as tensions rise on the Privy Council, the Guise's plan to reignite religious conflict.

With peace lying on a knife's edge, Catherine attempts to calm tensions by allowing the Bourbons to pursue the trade deal with England, and she halts the investigation into the Duke of Guise's arson involvement.

News of Edith's miracle spreads throughout Europe; the Bourbon's leverage an opportunity for England to exploit France; Catherine must return urgently to France when Anjou's temper causes damage.

Charles is ready to make his own rules, rejecting his mother's influence; with a rebellion on the rise, a mysterious plan is set, but when loyalty can be so easily swayed…miracles can happen.
