Half witch, half fairy, totally naughty! Mirabelle is Isadora Moon’s cousin, who we first meet in the author's famous Isadora Moon series.
Mirabelle is going on a school trip to a magical-creature sanctuary, and she can’t wait! Even being partnered with annoying goody-two-shoes Lavinia can’t ruin her day.
But when they accidentally let the bat kittens out of their enclosure things become a bit more complicated.
Can Lavinia help Mirabelle stay out of trouble? And can Mirabelle show Lavinia that maybe some things are worth getting in trouble for… ?
