After spending six months apart in Book Two, best friends Julie and Lydia are reunited at last! Julie has said good-bye to the mean girls, and Lydia is ready to apply her hard-earned friendship lessons to founding their own crew. But bad news interrupts their reunion: their friend Sukie's mother, ill for many years, has passed away. This shakes Lydia and Julie, who reevaluate their goals and decide to focus more on being supportive of the friends they have. Unfortunately, their well-meaning schemes almost immediately start to go awry, and everyone seems to be mad at them for reasons beyond their control. How can they be better friends when no one seems to want to give them the chance? As always, Julie and Lydia's hilarious back-and-forth notes form the backbone of the novel, in which Amy Ignatow reveals all-too-real truths about friendship and loyalty.
