"A Strange Day In July" by James Maggard
He threw with all his might, but the third stone came skipping back. Every time he threw it, it would come right back to him. He looked at his sister and his sister looked at him. They had no clue what was going on.
John and his sister came back the next day to see if the stone would come back to them. John said to his sister, I hope we were dreaming yesterday, his sister nodded her head. He picked a rock up and threw it, right when he did it came right back. The rocks in the sand made a sign and it said, "come back tomorrow and I'll tell you what's happening." He got scared and started to wonder what was talking to him. He grabbed his sister's hand and started to walk home.
The next day John and his sister came back to the creek. He threw the rock and he asked what was causing the rock to come back. He waited for a second, then the rocks spelled out "you're the chosen one." That day no one could find John and his sister. They were never found again.
