Quickly snatching up the stone, she said, "I wish I was back in Sarah's bedroom."
The stone glowed and her wish was granted. She ended up back in her pajamas and in Sarah's bed. She looked at the clock. She had transported back through time, but school had already started! Her second period class would be starting within another 30 minutes. If she wanted to be Jon again, she'd have to get to school and take that history test.
But then she thought whether or not she wanted to be Jon again. She still remembered her time with Earl and enjoyed living as a woman. She, in fact, preferred her life as a woman. But it wasn't who she was supposed to be.
She sat on her bed, thinking of what she wanted to do.
