About the title
A new student, Melanie, appears at Otto Leonhardt School - sweet, cheerful, though a bit naive. Felix takes an immediate liking to her, much to the annoyance of Ella and her friends, who suspect that Melanie is behind the string of petty thefts that have increased at school since her arrival. But when their suspicions nearly ruin a date between Felix and Melanie, it becomes the last straw, and the teenager decides to teach his friends a lesson by shrinking them to a tenth of their size. But when Melanie disappears along with a magical orb, things stop being a joke for the group. Could she really be involved in all this?
