Writing in the form of a journal this novel tells the story of odd goings-on in a girls boarding school in the late 1960s. The unnamed narrator is a student at the school, she is intellectual and somewhat aloof and associates with an intense clique of girls.
When Dora (one of the strangers) is found dead one night, a tragic accident is at first suspected. But then the rumours begin to circulate about Ernessa, the loner of the group. Is she a bad influence? A spoiled brat? Or is she a vampire?
