'A fun, frolicking adventure about five kids with a mystery to solve! Eleven-year-old Oli is spending his school holidays at Heroes Club, where kids can build friendships and learn about their emotions, but Oli just wants to be home where it's familiar, not-so-boring and he can play his favourite game. But when Oli and the other kids at the club see a stray dog who keeps disappearing into a soon-to-be-demolished building across the street, Oli and his four fellow heroes hatch a daring rescue plan to save the dog before it's too late. It's going to take bravery, some seriously smart teamwork and a few broken rules.' (Publication summary)
