An unexpected attack on Shanna & her friends prompts the team of monster hunters to venture to Greece, where they encounter an abandoned city and a haunting mystery. Something has caused a mass evacuation of the city, something sinister that will stop at nothing to get what it wants. And if the powerful force lurking in the wings isn't enough to tear the team apart, perhaps their own secrets are.
