For 15-year-old Sarah Owen, having a scientist father is a blessing and a curse. He doesn't bat an eye at her pyschic abilities, since he researches them; and she knows more about the invisible worlds of microbes, electricity, and gravity than most girls in the 17th Century.

Later, when the plantation owners find her and send her north to Salem, Massachusetts, her abilities get her into trouble.
