Threatened by the possibility of her destruction in a final battle between good and evil, Cassie must hope that her supernatural gifts are strong enough to obliterate the powers of evil. If victorious, Cassie will win more than she ever dreamed. But if she and Diana fail, the Power will go to those who seek only to destroy.

For Cassie and her Circle of witches, it's hard to imagine life in New Salem getting any worse. A band of powerful witch hunters is targeting the group, determined to destroy them one by one. And Cassie's half-sister, Scarlett, won't rest until she has a spot in the Circle - even if she has to kill Cassie to get it. The Circle's only hope against their enemies is Cassie's father's Book of Shadows - an ancient guide to the world of dark magic. But Cassie soon discovers that opening the book has grave consequences.

Lured into the most popular in-crowd imaginable, Cassie is intoxicated by her newfound strength. Caught between two members' consuming desires to use the coven's mysterious forces, Cassie turns to one of their boyfriends, Adam - and falls captive to her own dangerous love.

As the leader of the Secret Circle, Cassie is faced with impossible choices and new dangers at every turn...and one wrong move can break the Circle apart forever. Now, as Cassie battles her evil half sister, she faces a new and terrible danger. Black John's curse has been unleashed on the Circle, and it is up to Cassie to set things right.

Seduced by the Secret Circle, a coven of young witches whose power has controlled New Salem for 300 years, Cassie falls hopelessly in love with the leader's boyfriend and falls prey to dark powers.
