When she awakes, she's shocked to realize her new memories don't match what she's always remembered of that time. With the fate of her parents no longer unknown, Veronica is at peace, though she realizes a larger mystery is still to be revealed-her mother's pendant is somehow the key to her own destiny… and that destiny is fast approaching.
