Cold in Summer

The new girl in town meets a mysterious old-fashioned girl who can't seem to find her way home.
The girl didn't say anything. Her face held no expression.
Ariadne shivered. It was cool in the shade, and her hair was still wet.
"Hello," Ariadne said. No answer. "Um-I was just taking a walk. Is this your property?" Still nothing. She took a step toward the girl and stumbled on a fallen branch. She caught her balance and looked back at the tree, but no one was there.
The girl had vanished.
