The Overthinkers' Club is Nat Luurtsema's funny, warm-hearted illustrated diary series about the anxious inner world of the tween years. It follows Birdie, a champion overthinker who spirals a tiny worry into full-blown catastrophe, as she and her friends try to outwit their anxiety with a 'Happy List'. Illustrated throughout by Cécile Dormeau, the books pair a witty, diary-style voice with genuine emotional insight, navigating starting secondary school, blended families, self-image and shifting friendships. It offers real laughs alongside gentle, reassuring wisdom about worry — a good fit for readers who love Lottie Brooks and Dork Diaries and for any young overthinker who could use a companion for the awkward stretch between childhood and the teenage years.
