Sarah closed her eyes and concentrated on one thing she wanted to change about Jon. And when she opened them, she saw a girl sitting in Jon's place. But the girl looked a lot like Jon, except for obvious differences, like having long brown hair and D-cup breasts, and also the fact that she was wearing girl's clothes. She looked like she could have been Jon's twin sister. But, of course, she wasn't Jon's sister. She was Jon.
"Well?" Sarah asked, grinning.
"Well what?" the new female Jon asked. "Nothing happened."
"You mean you don't notice?" Sarah asked.
The new Jon stood up from the bed and walked to a mirror. She turned this way and that, but still couldn't figure out what was different ... if there was anything different at all. Sarah could have been playing a trick on her. Maybe those coins weren't even magic.
Sarah was amazed. All she thought about when she closed her eyes was: Jon is a girl. And when she opened them, he was. And he didn't even notice that anything was different!
She grabbed the coin that she gave him and looked at it. It looked unpolished, scratched even, almost like it was used. In a way, she supposed it was. She put it back in her collection and noticed the other nineteen glistening coins, all ready to be used on someone.
And she definitely had a few people in mind.
