The Court of Miracles

A fearless young heroine ventures into a Parisian underworld court of conspiring vampires in this sweeping alternate history.
The vampire King Louis XIV reigns supreme over a terrorized France, determined to protect his empire at any cost. When a mysterious renegade vampire named the Lady of Miracles ascends to power in an underworld Parisian court and claims the city for herself, Louis feels threatened for the first time in centuries.
His secret weapon to fight back? Mademoiselle Diane de Gastefriche, a young baronette who earned the king's trust through her own cunning and wit. He sends Diane to squash the new threat to his power. But King Louis has no idea that this feisty girl's real name is Jeanne Froidelac: she is an infiltrated commoner, whose secret mission is to destroy him and rid the world of the vampiric tyranny.
Caught between a vengeful king and a ruthless rival, Jeanne embarks on a quest that could alter the kingdom's destiny--and expose a powerful secret that she will do anything to protect.
