Who is Neferet from Betrayed: A House of Night Novel and what is their importance?

Neferet is the High Priestess, which is equivalent to the principal, of the House of Night School. Neferet is also a vampyre. She is a tall woman with almond-shaped eyes and dark red hair. Her eyes are a moss green color. She has a tattoo on her left breast, which is a goddess with upraised hands, which is a mark that all of the professors at the school possess.

In addition to being the High Priestess, Neferet is also Zoey's mentor. Neferet also has two personas. She shows herself as a caring mentor when she is acting in her duties at the House of Night. After hours, however, she has her own agenda and she is turning fledglings into some kind of walking dead creatures. Neferet is responsible for telling Aphrodite that she no longer has powers, but in fact Aphrodite still does have her visions underneath, Neferet is evil, but by the end of the novel, Zoey does not expose Neferet. Zoey simply tells Neferet that she knows what she's done and so does Nyx.
