Blood Born by Jamie Manning
Synopsis from Goodreads: Waking up in a coffin hungry for blood is only the beginning for sixteen-year-old Ava Blue. When Chance Caldon, the hottie who dug her up, tells her that she’s half vampire, Ava’s world really turns upside down.
Half vamp? Ava can’t believe it...she doesn't even know what that means! Not until Aldric, a thousand-year-old vampire, shows up and tells her it’s true--and that he’s the one who turned her. Then Ava truly begins to believe what she is. Now, she has to deal with a sudden and powerful bloodlust, the desire to see Aldric dead, and her growing crush for Chance. Ava knows she's a monster now, she can feel it; and her life is over.
But redemption isn’t lost. Aldric is giving her a chance to regain her humanity. The price? Kill a hundred vampires, or remain a bloodsucker forever.
So Ava sets out to get her life back. But killing vampires begins a battle that could destroy everything she is working toward. In the end, Ava's decisions will forever change her life and the lives of those she loves.
