Cyclone frowned. She said, “Like they’re Martians? Spacekids?”
I shook my head. “No. There are many worlds that exist alongside this one. Some of we interact with every day and simply do not notice because those interactions do not affect us in any significant way. Other worlds and the people that inhabit them require great effort to reach. And interaction with those worlds is often fatal for inhabitants of this one.”
Cyclone looked me up and down. She suddenly seemed unsure of herself. “Are you from another world?” she asked.
