Four stars **** nanotech is the center of the story
I forget where it originally appeared. It may have been _IASFM_ about ten years back.
*Fiction marked with an asterisk is located at an online magazine that lets you read the first part of the story free, then charges a small fee for the ending. Usually the fee is just a few cents.
