A young British witch, Mika Moon, follows three rules: hide her magic, stay away from other witches, and not attract attention. She was orphaned at an early age and grew up with strangers, so she is used to being alone. However, on her social media page, she posts videos of herself pretending to be a witch. Mika is convinced that no one takes it seriously. But soon she receives a message begging her to come to the remote and mysterious House That Doesn\'t Exist to teach three young witches how to control their magic. This is against the rules, but Mika goes. And she immediately becomes entangled in the secrets of not only her three students, but also the owner of the house, who has gone on an archaeological dig, a retired actor, a housekeeper, a gardener and... a librarian named Jamie. Handsome and prickly, he wants to protect the little witches because he sees Mika as a threat. An irritatingly attractive threat. But magic is not the only danger in the world. So Mika will have to decide whether it\'s worth risking everything for the new family she\'s been looking for for so long.
