The four Grace sisters love their quiet life in the country village of Chevis Green. To some, their insular world might seem dull, but the sisters never seem to run out of conversation, jokes, and pleasant ways to pass the time together. They truly are the happiest of families. That is, until Aunt Rona comes to town.
Rona intends to stay with the Graces indefinitely, and her meddlesome attitude immediately sets the sisters' teeth on edge. Throw in another unexpected houseguest, some potential suitors and a case of mistaken intentions, and the members of the Grace family suddenly find themselves quite out of their element. Will they manage to make it through the summer and return to their quiet ways?
