Priscilla Sum

Priscilla is just an average college student with an average life. Adopted at a young age by a wealthy "power couple" consisting of a museum curator and a real estate magnate, she's managed to keep a level head, and not make a big deal about herself. Archaeology is a passion of hers, so when a visiting group offers the once-in-a-lifetime chance to spend a week at a real dig site, off the coast of Greece, Priscilla seizes the opportunity to pursue what she enjoys.
Then... Disaster strikes. Priscilla wanted to believe that this was her Fate, but there seems to be other forces conspiring against her. The company organizing the dig is rumored to be engaged in some shady activity, her best friend since grade school reveals that he's slowly dying of a terminal disease, and most dramatic of all, her parents vanish overnight, leaving behind a letter telling her the truth:
They are gods, hiding in the guise of mortals so that a very powerful enemy--a demon they've been fighting for millennia--won't discover the hiding place of their divine power: The very island Priscilla will be visiting soon.
Is the archaeological group in league with the demon, or intent on discovering the hiding place first in order to stop him? Can she and her classmates find the hidden temple themselves? Will the demon come after her next?
