Publisher's Synopsis
Tenth in the series about Mirabelle, Isadora Moon's cousin. She's half fairy, half witch, and totally naughty!
When Mirabelle gets so cross with her brother, Wilbur, that she says she wishes he would just disappear, she doesn't actually think it will happen.
How will she get him to come back? Hopefully, a new friend can lend a ghostly hand. . .
