Most of the time, Leo loves Show and Tell at school. But when his teacher announces that next up is Tell Us About Your Dad Day, his tummy ties into knots and he tries to disappear into the corner of the classroom. His classmates can't wait but all Leo can think is ... 'how can I celebrate someone I've never met?' After searching high and low for clues about his father, he realises that he already knows someone cool, courageous and clever -- someone who's not his dad, but is his everything.
