Falk was the subject of a 1979 book, entitled "Lisanne: A Young Model", which piggybacked on the popularity of a
Jill Krementz series that included "A Very Young Dancer" and "A Very Young Rider". Falk's book followed her day-to-day activities as she toiled for the children's division of New York's Ford Modeling Agency, posing for "Seventeen Magazine" covers and the like.
