The Corner Park Clubhouse. For Belle, it's an empire. For Lola, it's a canvas. For Maisie, it's a refuge. For Sophia, it is home. Sophia and her lifelong best friends, Belle, Maisie and Lola, are reunited at their old favourite hangout - the Corner Park Clubhouse - after their first term at different high schools. But it soon becomes obvious that, in spite of pinkie swears and promises, they're drifting apart. The one thing keeping them together is the clubhouse, which holds special memories for each of them - and after what happened there last summer, it means more than anything to Sophia.

So when they find out it's going to be bulldozed, the girls set out in a race against time to save it - and their friendship - from demolition. From beloved author Davina Bell comes this sparklingly funny and heartfelt middle-grade series, for fans of Friday Barnes and Ann M. Martin's iconic Baby-Sitters Club series.
