In book 15 of the Mirabelle series by Harriet Muncaster, Mirabelle and the Enchanted Sea Globe, Mirabelle and her family are on holiday, staying in a lovely cottage by the sea. There's just one problem--they're not meant to be using magic. Can Mirabelle manage a whole week without any magical mischief? Of course not! But perhaps she can use a teeny bit of magic to create a special sea creature? Just for one night . . .
