Marked (House of Night #1) by P.C. Cast

After a Vampire Tracker Marks her with a crescent moon on her forehead, 16-year-old Zoey Redbird enters the House of Night and learns that she is no average fledgling. She has been Marked as special by the vampyre Goddess Nyx and has affinities for all five elements: Air, Fire, Water, Earth and Spirit. But she is not the only fledgling at the House of Night with special powers. When she discovers that the leader of the Dark Daughters, the school’s most elite club, is misusing her Goddess-given gifts, Zoey must look deep within herself for the courage to embrace her destiny—with a little help from her new vampyre friends (or Nerd Herd, as Aphrodite calls them).
