Kat flipped frantically through her spellbook. "There has to be something," she said over and over again. "There has to be something."
"Kat, I'm scared," Dan said.
"You're not the only one," Kat replied. "I'm absolutely terrified. I don't want to be your mother, and I don't want anyone thinking I put out, especially not for my brother."
"We didn't have sex," Dan protested.
"But when I turn up pregnant and you turn up missing, everyone will think you ran away because you knocked me up. You know how rumors get started. So be quiet while I find the right spell." Kat suddenly realized that, while she flipped through the spellbook with one hand, she'd started rubbing her belly again with the other. Remembering what Dan had told her, she sat on her other hand.
"Here we are," Kat said, feeling triumphant. "This one's called 'Reversal,' and it promises to undo any spell that the spellcaster got wrong." She scooped up her wand and, skimming over the spell, pointed the wand at her womb. "Stellen Sie mich frei ein!" she called out.
Dan and Kat started feeling woozy. Kat clenched her eyes as the light in the room became painful. Everything swirled around them. After a minute, the room seemed to settle down, and she opened her eyes.
Or tried to. Everything stayed black. She cast her head back and forth, looking for the slightest glimmer of light, but she saw nothing. "What happened?"
"Um, Kat?" Dan's voice was still in her head, but sounded much closer and louder. "How closely did you read this spell?"
"What do you mean?"
"It isn't called 'Reversal,' it's called 'Renewal.' And it doesn't promise to undo broken spells, it promises to set the balances straight."
"What do you mean? How do you know?"
"Because we've switched places. I have your body, and I hear your voice in my womb. I'm pregnant with you."
