Sid and Michelle break up. Cassie starts sleeping around to forget Sid. In the midst of art coursework and the annoying Pandora, Effy must help them all sort things out.

What's the matter with Cassie? She's back together with Sid, Chris is on the mend, Michelle and Tony are back with each other and A-level exams are finally over. So to celebrate, Sid has organised a dinner party where everyone can try to get along. But how can they? Jal is lying to Chris, Chris is lying to everyone, including himself. And when it finally gets too much, Cassie runs. She runs and runs and keeps on going - until she arrives at a totally magical place, where the people are friendly and she can get along. But can she be happy?
