The bad news is that Perce nearly set their house on fire. The good news is that they did it by magic.

But they’re only a child, and their new powers are out of control. They need to learn, and learn fast. That means they need a teacher. And who better than a travelling wizard: the magnificent, long-bearded and slightly mad Gideon the Effervescent?

Can Perce learn to control their magic? Will Gideon ever master the perfect barbeque? And when trouble comes to Whetstone, can teacher and student work together to save their friends and family?
