House of Night: Betrayed by Kristin Cast (author) and P.C. Cast (author)

It seems that (un)life is going well for Zoey Redbird. She has settled in at the House of Night, and is coming to terms with the immense powers the vampyre goddess, Nyx, has given her. She even has a boyfriend … or two. Best of all, Zoey finally feels she has found somewhere she belongs. Then the unthinkable happens. Human teenagers are being killed – and all the evidence points to the vampyres at Zoey’s school. While danger stalks the humans from Zoey’s past life, she starts to realise that the very powers that make her so unique could also threaten those she loves. And when death strikes inside the House of Night, Zoey finds herself facing a betrayal that could break her heart and jeopardise the very fabric of her world.
