A story for those who dare to be different ... In the depths of a wood, in an old hollow tree, Mouse Four is one of a family of four baby wood-mice. Born with a somewhat rebellious and unconventional nature he refuses to choose a name for himself (as a wood-mouse must), and upsets his family with his dreams and strange ideas. Refusing to fit into normal wood-mouse life, and rejected by his family, he leaves and goes to live in a barn. He builds a nest in an ancient tractor, but one day the tractor is moved out and a microlight is pushed in. He explores the wonderful flying machine with great excitement, then he falls asleep under the seat. He wakes when the engine is roaring at the end of the runway. It's too late to jump out. His life is transformed and flying becomes his passion. Can he now discover a name that is truly him, and win his family's acceptance too?
