Humans have been keeping secrets for generations and using cryptology to make sure those secrets don't fall into the wrong hands. From the development of ancient Greek ciphers, to the creation of the Enigma and today's CRISPR technology, codes and codebreakers have changed the course of history. Today cryptology addresses cybersecurity and the ethics of hacking our own genetic code. Cracking the Code reveals the history of codes, explores why humans keep secrets and introduces us to coding heroes like the Navajo Code Talkers from World War II. Codes have defined human history and will map our digital future. Will you be the next codebreaker to unlock the mysteries behind the codes that shape our world?

Years before Rosa Parks famously refused to give up a bus seat in Montgomery, Alabama, Viola Desmond took a similar stand against racial segregation in New Glasgow, Nova Scotia. On November 8, 1946, she was arrested for refusing to move from the "whites-only" section of a movie theater. Her heroic act inspired Black community leaders and made her a symbol of courage in the fight against inequality. This story of Viola's life is based on rare interviews with her sister Wanda Robson, who spent her life championing her sister's story and was successful in getting Viola a posthumous pardon that recognized she was innocent of any crime. From their childhood in Nova Scotia to Viola's career as a teacher in a segregated school and, later, her role as a pioneer in Black beauty culture, young readers are introduced to the girl and the woman who went on to become the face of the civil-rights movement in Canada.
