Finally, Darrell Rivers is going through her last term at Malory Towers. 6 years had passed quick as a blink of an eye. She becomes the Head Girl, but not everyone follows her directions. There is a girl in the Sixth form, Amanda, who can never stop boasting, and Jo, a girl in the same form as Darrell's sister, never knows the differences between right and wrong. They all learn their lessons in the end with the HUGE mistakes they make and farewell!
