Now that you are mine (1997-2000) follows and chronicles the lives of female prostitutes on the streets of the red light district in Copenhagen. Simultaneously visceral yet compassionate, the images from Now That You Are Mine expose and undermine the subjection of women at the hand of male chauvinism. Finn Thrane of the Museet for Fotokunst in Denmark writes:

"Søndergaard goes beyond the walls of the private sphere, following the women and the 'fly on the wall'. Released from these conventions, Søndergaard's work embodies and explores the dualities of her own role as an artist, but also as a woman. The artist was personally and daily subjected to harassment by male customers on the street where she lived. Her own subjection to this male gaze marked the beginning of the project. She realised that she was not "seen". That she existed only as a projected fantasy of a woman for the male customer. It is this fantasy her work ruthlessly exposes, a sexual fantasy in harsh contrast to the reality of infected needle sores and bruised skin."
