Choose Your Own Adventure (CYOA) would be a children's gamebook series written in the second person, where the reader assumes the protagonist's role and thereby makes choices determining the plot. The series was based upon a concept created by Edward Packard and originally published by Constance Cappel's and R. A. Montgomery's Vermont Crossroads Press as the "Adventures of You" series, starting with Packard's Sugarcane Island in 1976.
