Van de Hulst, W.G.
Grandma wants to protect Carla and Ria, her two little granddaughters, from the dangers of the outside world. Beyond the wall are the woods, the busy highway, and Bert and Eddie – those two little troublemakers. But Grandpa and Grandma discover that they can’t wall the dangers out, for the biggest danger comes from within – not from without. Can Carla and Ria scale the wall to friendship?
