Gone-Away Lake, book 1: Gone-Away LakeElizabeth Enright1957

When Portia sets out for a visit with her cousin Julian, she expects fun and adventure, but of the usual kind: exploring in the woods near Julian's house, collecting stones and bugs, playing games throughout the long, lazy days.

But this summer is different.

On their first day exploring, Portia and Julian discover an enormous boulder with a mysterious message, a swamp choked with reeds and quicksand, and on the far side of the swamp...a ghost town.

Once upon a time the swamp was a splendid lake, and the fallen houses along its shore an elegant resort community. But though the lake is long gone and the resort faded away, the houses still hold a secret life: two people who have never left Gone-Away...and who can tell the story of what happened there.
