Seven

"You may be a seventh daughter," he smirked, walking around me, "but you can't win against the power of a seventh son."
Sirena Argent is one of the most powerful of the Silverbark Circle, the most powerful coven in all of Aelburn. Sirena is a seventh daughter of a seventh daughter, meaning she has the power to reign over Aelburn with her magic ever since the murder of her older sister. However, no ruler of Aelburn was ever part of a coven and her subjects are starting to doubt her. They doubt her even more when a seventh son of a seventh son comes to Aelburn saying that he will take over. What will happen to Aelburn? And are the rumours about the seventh son true?
