"I wish I was in Jon's bedroom." The stone glowed and Karyn disappeared from the sidewalk in front of Jon's house and reappeared inside his bedroom. She looked down at the still-sleeping Jon and smiled. Then she reached for him and shook him awake.
"Huh?" Jon groggily said.
"It's me, Jon. I wanted to use your stone."
