Everyone on Joshua's side of the wall knows one thing: the wall keeps you safe. you must not cross to the other side.
Joshua kicks his football into a building site and discovers a secret tunnel. It leads through pitch darkenss under the Wall and into forbidden terriroty,where a boy like him shouldn't stray. When joshua emerges into the light of the other side, his world is turned upside down-with kindness, terror and violence, and a debt he can never repay.
One thirteen-year-old cannot tear down a wall.but why should he have to choose a side?
