The hilarious new picture book from the record-breaking Adam Kay and Henry Paker.

Meet Simon. Simon is the hero of this story. But unlike most heroes in most stories, Simon is a piece of snot. He lives with his family in the left nostril of a girl called Phoebe.

Follow Simon on his hilarious and extremely slimy adventure as he learns about everything snot does to protect our bodies – a fascinating and uplifting journey of self-discovery about how brilliant and important he really is.
