This is the second book in the TJ series. The girls have graduated into Form Two and TJ hasn't let go of her pranks. The author carries on the story with the same characters. An important character, Mary Beth, is introduced in the scene, and she plays havoc with the firm and beautiful friendship between TJ, June and Marsha.
The "North Pole" incident between TJ and Mary Beth is simply out of this world; and the "VIP gate" episode is hilarious. Unfortunately for TJ, Marsha and others, the "VIP gate" and the "North Pole" are sealed permanently.
