Five Have a Wonderful Time by Enid Blyton
Published October 24, 2022

Off on another adventure, this time the Five are camping in a field that also happens to have a travelling circus nearby. At first they’re not friends but the return of Jo who we met in a previous book softens them, and together they manage to rescue a scientist who has been kidnapped and is being held prisoner in the crumbling ruins of a castle. As you do. Fun, but pretty standard at this point for the group.
