This moving novel for young readers explores the importance of legal awareness and historical memory in Italy. It tells the story of Nadia Nencioni, a young girl who lost her life during the 1993 Mafia bombing in Florence. By connecting this tragic event from the past with a modern-day school setting, the author—who is a real-life anti-mafia prosecutor—encourages the new generation to understand the consequences of organized crime and the value of justice. It is a powerful story about light, hope, and the refusal to forget those who suffered.
