"This hilarious new illustrated diary series will be catnip for 9+ Lottie Brooks fans." The GuardianThe first book in the brand-new illustrated series filled with LOLs, BFFs, drama and crushes and lots of overthinking! For fans of Lottie Brooks and Dork Diaries. Birdie is an overthinker, and she has a lot to overthink. Her BFF Chloe wants new friends (BETRAYAL), she will be a teenager in one year (BREATHE), yet owns ZERO bras (surely some mistake?!), and a boy at school maybe has a crush on her (BUT HOW TO BE SURE?!). So Birdie has made a Happy List to tackle all the awkward and emotional challenges of being a tween. THEN she will stop being an anxious ball of stress and be happy!That's the plan anyway...
