One of the most Stark Riches to Rags stories I have ever seen, pornstar Margo Stevens.

Photographer Lee Jeffries has devoted much of his time to capturing the overlooked faces of homeless individuals across the globe. Trekking from London to Paris to Rome to New York, the UK-based artist has made it his personal mission -- he's actually a full-time accountant by trade -- to attach a human face to the epidemics of poverty and addiction.

Far from voyeurism, Jeffries is part documentarian, part activist; a man who seeks out the untold narratives behind homelessness, delving well beyond imagery. Case in point: his recent trip to Miami, FL where he met Margo Stevens, a former adult film star now living on the streets of the dangerous Overtown neighborhood. Jeffries spent nearly two weeks there getting to know the enchanting and tragic woman whose "riches to rags" saga hit the photographer particularly hard.

"I found her story quite stark," Jeffries explained in an interview with The Huffington Post. "She was a well-known porn star in the 1990s who escorted for a living. She's beautiful and obviously lived the life, had whatever she wanted... but her fall to what she has become today really hit me hard." According to Jeffries, Stevens now sleeps in an abandoned 12-foot by six-foot garage with four to five other homeless women she looks after on a daily basis, most of whom are addicted to heroin, living off the money they make as sex workers.

Stevens' circumstances may be familiar at first glance -- as a young woman she worked in a strip club in Cleveland, eventually transitioning to the adult film industry and escort services. She made money for several years, and when her luck in the industry ran out, she moved to Miami, slipping into a pattern of homelessness, drug use and prostitution. But her connection with Jeffries reveals the touching humanity of her unique experience. As the photographer's stunning images reveal, the labels "prostitute" and "user" only skim the surface of her being. She is a mother-figure to those around her, a protector and respected friend in the neighborhood, who, like other addicts lacking the money or community support to alter their lifestyles, uses sex work as a means to an end -- freedom and survival.
