The night is especially dark before the dawn... High school student Cassie no longer feels lonely since she moved to the town of New Salem and joined the secret circle of witches - her new friends have become almost family to her. But now that the witches have fallen under the control of powerful evil spirits, Cassie has no choice—she must turn to the dark side. Trying to save her friends and her lover, Adam, the girl suddenly finds an unexpected ally and experiences an unprecedented temptation. Enemies come from all sides, and Cassie, meanwhile, tries to keep her heart open and her soul unsullied. But she, like no one else, knows that practicing magic comes with a heavy price, especially when it comes to the mysterious Book of Shadows. Will Cassie be able to defeat the darkness once and for all... or will the secret circle die?
