Meg, the youngest in the Copeland family always feels out of place. She has to share a room with her older sister Sally and they constantly bicker. Everyone in the house thinks she's too rowdy and she is always getting into trouble without meaning to. To make it all worse, she's struggling in school and probably won't move on to the next grade. The promise of a room all her own seems to be the answer to everything. But when Grandma Kent unexpectedly comes to live with the Copelands, instead of a room to herself, Meg has to learn to live with yet another person. But what Meg doesn't see is that these new adjustments can be for her benefit, too.
