“The Sisterhood of Night” has added another member, as Deadline reports “The Chronicles of Narnia” star Georgie Henley has boarded the teen secret society drama, joining “Moonrise Kingdom” star Kara Hayward as well as young actress Morgan Turner, who both signed on last week.

Deadline reports Henley has landed the lead role of Mary in the film, a member of the New Jersey suburban secret society The Sisterhood of Night, which is exposed at the hands of Hayward’s character Emily, the high school’s resident gossip girl. The small suburban town the girls live in is turned upside down as a witch-hunt ensues, with townspeople and the blogosphere trying to discover exactly what goes on in the woods at night. Marilyn Wu scripted the film back in 2007, and Caryn Waechter is on board to direct the film that will deal with the loneliness, tragedy and humor of adolescence all while growing up in the digital age.

Henley, who is still most known for playing youngest sibling Lucy Pevensie in all three “The Chronicles of Narnia” adaptations, recently completed filming on “Perfect Sisters” (formerly “The Class Project”) opposite Abigail Breslin.
