Neferet is the High Priestess at the House of Night. This means that Neferet is in charge of everything, much like a principal but with much more power. Neferet is a beautiful, tall woman with a commanding presence. Like all adult vamps, Neferet bears her mark as well as an elaborate tattoo on her face that only serves to increase her beauty.

Neferet becomes Zoey's mentor, and realizes that Zoey has special powers even beyond her filled-in Mark. Adult vamps know many things and even though Zoey does not confide in Neferet in the beginning, she learns that Neferet can be trusted.
