Kit may be the youngest wizard ever, but she sure doesn't feel like the best wizard. Her magic just keeps going wrong, and other weird stuff is happening too: talking animals, exploding fireballs, and a very strange new arrival in the local park. Even Dogon (the half dog, half dragon) is droopy! So Kit and her two best friends—animal-whispering Alita and studious Josh—set off with Faith the librarian to investigate this wild magic that's causing so much commotion. Their journey takes them to a Scottish loch, where they meet an eco-conscious wizard and some very grumpy mermaids (careful, they pinch!). But the danger is greater than they imagined, and it will take everybody's help to set things right again.
