At Arsenyev Academy, Vera Morozova is invited to a secret seminar meant for six students. With her, there are seven. Then she finds a photograph from 2003: seven students again, though the archives list only six. The seventh girl’s face has been crossed out, her name erased — and she looks disturbingly like Vera. When the student helping her investigate dies, the Academy’s oldest secret becomes dangerously personal.
