Charlie and the Chocolate Factory book by Roald Dahl

An unexpected inheritance gives Greg Heffley's family the chance to transform their home. But they soon discover that the home renovations aren't quite what they had hoped for. As soon as they tear down the walls, all sorts of problems start to arise. Rotting wood, toxic mold, an unwelcome neighbor, and something even more sinister than all of them make Greg and his family wonder if the renovations are worth the trouble. Will the Heffleys be able to stay when the dust finally settles... or will they have to leave town?
