Firstly, what a title! The appealing front cover leads you in to this funny, playful and informative book about what hands are, what is inside of them and how they work. The story starts on the endpapers as two aliens (Quog and Oort) crash land their spaceship on Earth and need help in order to get to a birthday party on time. You, the reader, help them reach Kevin’s party by interacting with the book and teaching them about hands, skeletons, muscles and nerves. It is a great premise and children will enjoy such interactions as placing their hands on the page to be “scanned” to show muscles and demonstrating how nerves work by turning over a page with their eyes closed. As Quog and Oort find out more about hands so do we and the grateful alien pair are aided on their journey….
