The Girl, the Dragon, and the Wild Magic

Magic isn't easy...

Rhianna is failing out of magic school. She's very clumsy, even though she tries really hard. After she causes her biggest mess ever, a wizard appears with some astonishing news—Rhianna's magic is, in fact, stronger than anyone else's. She's a Wild Talent, which means that she possesses a pure form of magic that is full of power and energy.
The hitch? Well, it's very hard to control the wild magic. And it tends to suck up all the other magic around it. So when a dragon comes to town, it's up to Rhianna to save the day . . . if she can.
