'Ollie was small – like a pickling jar or a shoe box. Augustus was big – like a fridge or a table. They did most things together, including cycling, painting, dressing up, digging (Ollie's favourite thing) and stick collecting (Augustus's favourite thing). But Ollie is about to start school, and he has one major concern: who will keep Augustus company? He decides to search for a playmate for his enormous companion, but good friends are hard to find, especially for your best mate. In the end, Augustus shows Ollie that he doesn't mind waiting for him and that he can enjoy his time at school, worry-free.'
