Mirabelle's mum is a witch, her dad is a fairy, and she is a bit of both! Mirabelle is desperate for a brand-new pair of magical roller skates, but Mum and Dad say she's got to earn the money to pay for them herself. Earning money sounds tricky-how's she going to do it? Of course! She'll set up a business. But a business doing what. . . ? She has a go at dog-walking, but things get a little bit out of hand. And when 'things getting out of hand' include the dogs' leads, that's not good for business. Maybe something that keeps still would be easier. Something like making and selling enchanted charm bracelets! Can Mirabelle make a success of her get-rich-quick scheme? Or will being the boss end up being more trouble than it's worth?
