The girl looks like a normal, average schoolgirl, except her feet are slightly on the small side and her hair is very, very shiny. Perhaps you decide that the old lady is the girl’s grandmother. She looks like she’s probably saying, ‘Come along, dear. Let’s get home so your old gran can make you a batch of biscuits.’ You smile, thinking, What a lovely granny, and what a typical, ordinary girl. They must be going on a stroll together – the sort we humans go on all the time. Well, you were right about one thing – the old lady is the girl’s grandmother. But everything else you thought was wrong. Totally, utterly wrong. For a start, there’s nothing typical or ordinary about the girl. She’s a fairy, and her name is Elly. If you were a fairy expert, you might’ve noticed that she has exactly ten freckles and that her fingers are slightly shimmery. You wouldn’t have seen her wings, though, because they were hidden beneath her clothes. Her grandmother is a fairy, too. But Elly’s grandmother isn’t exactly lovely.
