The holidays are coming to an end, and many schoolchildren are not at all happy about it. But not 12-year-old Emma Willick. She's just waiting for the closed Wellsworth boarding school to open its doors again. After all, it was there that the girl made cool friends, learned a lot about her father, who disappeared many years ago, and, of course, exposed the gloomy order of Black Hollow Lane! Just before leaving for school, Emma finds a note from her father, in which he asks her to be safely hidden his ancient medallions, because the Order is hunting for them. Emma, of course, complied with the request. But she couldn’t even imagine that a seemingly ordinary trip to the bank would turn into a complete disaster! And her close friend will be accused of a crime that she did not commit. Emma must muster her courage, protect her friend, and once again challenge the Order of Black Hollow Lane!
