Everyone at Hogwarts knows the rules. Don’t cross Mattheo Riddle. Don’t start problems with the Slytherin boys. And if you value having an intact nose, don’t insult their little sister. Celeste Rosier is a second-year Slytherin who couldn’t be more different from the people protecting her. She’s quiet, polite, terrible at standing up for herself, and somehow manages to get herself into trouble without meaning to. Most students assume she’d be an easy target. Until they realise who follows her around. For reasons nobody fully understands, Celeste has been unofficially adopted by Hogwarts’ most feared group of students. Mattheo Riddle treats her like his own little sister. Theodore helps with her homework. Blaise spoils her rotten. Enzo lets her braid his hair. Draco acts annoyed whenever she’s around while simultaneously threatening anyone who upsets her. And Pansy has practically taken over the role of protective older sister. The result? An entire school terrified of a twelve-year-old girl who wouldn’t hurt a fly. As Celeste navigates Hogwarts, secret passages, Quidditch matches, detentions, and the chaos constantly surrounding her older siblings, she slowly discovers that being protected by the most dangerous people in school isn’t nearly as glamorous as it sounds. Especially when those people keep starting fights. And dragging her into the aftermath.
