When Portia Blake and her family came back to Gone-Away Lake, it was to move into an old house locked up tightly for nearly half a century. Next to discovering Gone-Away the summer before, nothing so exciting had ever happened to Portia and her cousin Julian. Then began an enchanted summer of exploration and discovery, as the old house slowly revealed its surprises and its treasures.

This is the sequel to the book, Gone-Away Lake, by Elizabeth Enright. (Summary from an original jacket)
