I'm looking for the title of a book I read in the mid 90's, but it may have been older. It was about a girl who was a clone of a female scientist who had died before her research was completed.
She lived with a family who knew her secret and there was some future technology similar to Google Maps that would warn her not to go to certain parts of the city because of riots but it was really to keep her from running into her clones.
I remember a part of the book saying that the clone experiment was a failure because all the girls grew up with different talents and interests.
I don't know if it was a standalone book or part of a series but it kind of haunts me and I would love to revisit it.
