Young Ava Evergreen must earn the title of apprentice witch before she turns thirteen. And if she doesn't do this, she may lose her magic forever. There seems to be no reason to worry, because for most young witches and wizards the entrance exam is quite simple - you need to live one lunar month in another city, help its residents with your magic, do good and fly on a broom. It would seem, what problems? But Eva only has a pinch of magic. And sometimes it works in a rather unpredictable way, and the witch ends up with, for example, a cabbage field instead of a flower garden. And when she arrives in the seaside town of Auteri, where she has to pass her test, the residents are disappointed - after all, they need a full-fledged witch, and not a half-magical girl. But when Eva opens her semi-magical repair shop, she soon discovers that she manages to fix not only breakdowns, but also human relationships. And her sincere desire to help the city, which she loved with all her soul, brings to life such magical things as friendship, love and mutual assistance. And in the hour of real testing, they will turn her tiny magic into a mighty force capable of reversing a monstrous storm.
