But when she is unable to give her husband heirs to the French throne, she resorts to the darkest magic possible in order to conceive only to discover, in the end, that her most beloved child, King Henri III, will be the author of the bloodshed she so fears unless she risks her life and kingdom to destroy him. The Medici Queen is the tale of a country torn apart by religious strife and the savage internecine wars of the royal Valois, Bourbon and Guise dynasties.
