Through their instant messages, three inseparable friends have shared the ups and downs of high school. They've survived a flirtatious teacher, a witchy classmate, a pot-smoking smoocher, a Care Bear-toting stalker, and much, much more. Now it's their senior year, and Angela, Zoe, and Maddie--otherwise know as the winsome threesome--are feeling invincible. Too bad Jana, the Queen Bee who made their sophomore year a nightmare, is on the warpath again. This time she has it out for good girl Zoe, and it's up to Maddie and Angela to defend their friend. Not that Zoe, who's deep in love with Doug, seems to notice. A series of pranks escalates, culminating in a senior prom that no one will forget, even if they want to! And it will be up to Zoe to finally take action and make sure the power of the winsome threesome prevails.
