Marked

Enter the dark, magical world of the House of Night series by bestselling authors P.C. Cast and Kristin Cast, a world very much like our own, except here vampyres have always existed.
One minute, sixteen-year-old Zoey Redbird is a normal teenager dealing with everyday high school stress: her cute boyfriend Heath, the school's star quarterback who suddenly seems more interested in partying than playing ball; her nosy frenemy Kayla, who's way too concerned with how things are going with Heath; her uber-tough geometry test tomorrow.
The next, she's Marked as a fledgling vampyre, forcing her to leave her ordinary life behind and join the House of Night, a boarding school where she will train to become an adult vampyre. That is, if she makes it through the Change—and not all of those who are Marked do.
It sucks to begin a new life, especially away from her friends, and on top of that, Zoey is no average fledgling. She has been chosen as special by the vampyre Goddess, Nyx. Zoey discovers she has amazing powers, but along with her powers come bloodlust and an unfortunate ability to Imprint with Heath, who just doesn't know how to take "no" for an answer. To add to her stress, 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 group, 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.
