How come Violet is suddenly not into drawing? Who etched the words 'I Am Bug Man' inside my desk? Why is Mom suddenly acting like she has a secret?

Nobody said starting the last year of primary school would be easy, and Penny Lowry's anxiety means a million questions are always spinning through her thoughts. Luckily she's got a lot to look forward to, like her favourite after-school activity, Art Club, and seeing her best friend Violet again after spending the whole summer apart.

The thing is, Violet has been acting weird ever since she got back. She never wants to hang out anymore, she says Art Club is for babies, and she spends all her time with Riley, the meanest girl in school. Did Penny do something wrong? And if she did, can she undo it?

In this sweet, tender and funny introduction to a lovable kid figuring out how to manage her anxiety, the author of the #1 bestselling Pretty Little Liars series gets to the heart of how to let go of the friends who aren't right for you - and how to make room for the ones who are.
