What’s it about?

The story.

Twelve-year-old Birdie is brilliant at overthinking. She starts with a tiny worry, spirals into worst-case scenarios, then catastrophises until the whole thing is completely overwhelming. Her best friend Chloe is pretty good at it too, so together they hit on a plan: a Happy List of things that might cancel out the anxiety. At first it works – dancing, gratitude and a good night's sleep really do help. But when Chloe adds 'make new friends' to the list, Birdie decides that's just one more impossible thing to fret about. Told with warmth and a very witty diary-style voice, and illustrated throughout by Cecile Dormeau, this is a sharp, empathetic portrait of that awkward stretch between childhood and the teenage years. Nat Luurtsema navigates starting secondary school, blended families, self-image and shifting friendships with real comic flair and a lot of gentle wisdom about worry – a reassuring, funny read for any young overthinker.

Fit check

Right for your child?

Where it lands by age

Aimed at 9–12s (the publisher pitches it at 10+), reading independently. The funny, diary-style voice and short illustrated chapters carry reluctant readers, while its handling of anxiety and secondary-school worries speaks especially to tweens on the cusp of that transition.

Why it lands

Why they love it.

Why kids love it

Birdie's runaway worry-spirals are painfully, hilariously recognisable, and her Happy List gives readers something to try themselves. The funny diary voice and Cecile Dormeau's illustrations make a book about anxiety feel like chatting with a friend who really gets it.

  • Being understood finally
  • Friendship and belonging

Why parents love it

Luurtsema handles anxiety, changing friendships, blended families and self-image with genuine wit and empathy, never turning it into a lesson. It's reassuring for anxious tweens and a natural conversation-starter about worry and mental wellbeing.
