Ever since she discovered her affinity for magic, seventeen-year-old Anouk has been desperate to become a witch. It's the only way to save her friends, who, like Anouk, are beasties- animals enchanted into humans. But unlike Anouk, the other beasties didn't make it out of the battle at Montélimar in one piece. With her friends now trapped in their animal forms and imprisoned by Prince Rennar, Anouk is forced into a sinister deal with her sworn enemy and a deadly rival by fire- deep in the forest of Bavaria- to become a witch. But Anouk soon realizes that the beasties are not the only ones in danger. The fiercest coven of witches that history has ever seen has unleashed a plague on London, and the Haute may not be strong enough to fight on their own. With the fate of the two worlds hanging in the balance, Anouk must unlock her power and forge new alliances to prevent tragedy. But what happens when she discovers she might not be the witch she always believed she was?
