Eleven-year-old Rory is struggling to deal with his mum's departure and the tiresome fame of his celebrity-chef-dad. He always seems to be in trouble at school as well as at home. If he can't bring his temper under control, he could soon be facing his worst nightmare, being sent away to boarding school. One day he makes a shocking discovery. A stranger is living in their shed! A stranger who soon becomes the best friend he's ever had. Rory doesn't like many people. That's probably why he likes Angus - he's different. Angus is intelligent, smelly and often infuriating. He always understands how Rory is feeling and knows what to say. But who is he? What is he? And why does he know so much about Rory? Through adventures and arguments, dreams and dilemmas, Angus helps him more than he realises. By the time Rory discovers his identity, it's no longer important. It doesn't matter who he is. What matters is that Angus is no longer the stranger in the shed.
