Fear - Percy Jackson at Hogwarts Three

Sequel to Falling
Hero's are lost and scattered across the globe. Some finding hope, others letting it slip from their fingers. When the two worlds of demigods and wizards first collided it was expected to have some minor issues. Never was a fight as big as this one predicted to fall upon the weary heroes. Yet here they are, two years later and still struggling to survive a single prophecy that can still doom them all.
