Gone with the Wand by Margie Palatini, illustrated by Brian Ajhar

From chapters.ca:
Bernice, the godmother of all fairies, is having a very bad wand day. A very bad wand day, indeed. It's time to look for another fairy tale! It's up to Edith the tooth fairy to help Bernice find her magical powers again, or else Bernice will be forced to give up her wand. Margie Palatini's heart- warmingly hilarious story about helping friends and finding your place in life along the way, and Brian Ajhar's beautifully fun illustrations will have both children and adults giggling out loud.
