NT ASFM (Asimov's Science Fiction) APR/May 2006 - science fiction/romance
Kayla is hired to record a family wedding, week-long reunion for an old woman who is a Mars Colony administrator. Kayla is more than a cameraman, she is what is called a chameleon. She takes a nano that records vision, hearing, taste, touch, and smell. After the job she downloads her recording and loses all memory of it. The old woman who wants the wedding covered is especially interested in one of her extended family, a handsome young man named Ethan.

The science fiction background is mainly a framework for a what ends up being a love story. A pleasant tale.
