Wizards of Tomorrow

What happens when a new threat appears?

With three monsters defeated so far, Sophia, Noah, Ava, and Mason are starting to feel like they've got this monster-fighting thing down. But then the next monster shows up. This one is different. It's dangerous, and it can get inside their minds and control their magic. When one wizard turns against another, will they ever be able to defeat the monster?
