" I want you to remember something. Zo. It's important, and it'll make more sense when you have yourself together again. I'm gonna leave here and get another chance at life.You're gonna be a big, famous vamp High Priestess. That means you're gonna live like a gazillion years. I'll find you again. Even if it takes a hundred of those years. I promise you, Zoey Redbird, we'll be together again." Heath pulled her into his arms and kissed her trying through touch to show her that his love was never-ending. When he finally forced himself to let her go, he thought he saw understanding in her haunted, shocked gaze. "I'll love you forever, Zo."
