In the last chapter of P.S. I Loathe You, Massie loses all her friends, except Claire, due to being too bossy. In Boys R Us, Massie disbands the Pretty Committee (also known as the PC) and starts a new clique called Massie and Crew (also known as MAC). MAC is made up of model actresses that Massie Block and Layne Abeley hire from the Shooting Stars Talent Agency. The Talent Agency is run by Layne's Aunt Peace, whom she fondly calls "P".
