Billy Plimpton is an eleven-year-old boy with a big dream. He wants to be a stand-up comedian when he grows up: delivering pinpoint punch-lines and having audiences hang on his every hilarious word. A tough career for anyone, but surely impossible for Billy, who has a stammer. How will he find his voice, if his voice won't let him speak? The idea for this story came from Helen Rutter's son, who has a stammer: she wanted to write the book that he would love to read, starring a child like him.
