Night Cries (Hunters of the Dark #2)

An unexpected attack on Shanna Hunt and her new friends prompts the team of monster hunters to venture to Greece, where they encounter an abandoned city, ancient ruins, 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 the secrets they are keeping from each other are.
