Young pure-blood witch Lily attends her first year at the esteemed Gerhardt School of Magic to learn the magical arts. Having lost her parents as a newborn, she lives with her godmother and her aunt Bella, one of the teachers at the school.

As the year progresses, strange things begin to happen that indicate that Sinestra, the dark witch responsible for the murder of Lily's parents, has returned. But when Lily and her friends are suddenly sucked away to a trap that was orchestrated by Sinestra, Lily learns a horrifying truth not only about herself but also about the death of her parents-a truth Bella has known all along but never revealed to Lily.

Fans of Harry Potter will love The Return of Sinestra, which reveals that what matters is the bond between people-and that blood is not always thicker than water.
