This is Tiger, she was living in someone's backyard in an area of the city north of me. Very long story short, she was captured in late January when she was a year old and I took her in to be with her brother from the same litter, who I was fostering since late October of last year (another long story). Her only interaction with humans was once in a while when she was given food by the person living in the home. 
At a year old, it's very, very difficult to socialize a feral cat and get them acclimated to the indoors. She wrecked the hell out of my bathroom when she first arrived in my place, and it's been a journey and saga with her.
About 1.5 months ago, it felt like there was little to no progress with her and I was very, very close to giving her up. However, it seems that she is being socialized, just very, very slowly.
After much hissing, biting, swatting, running away (the last one she still does once in a while and she almost swatted at me once when I offered my finger to pet her), etc, now she will let me pet her either when I'm hand feeding her (wet food) meal twice a day or if I'm giving her a treat.
But at least she's now becoming more comfortable here. Occasionally she'll either hang out by the window on the couch or rest at the end of the couch (while I'm on my side of the couch), which seems like a good sign. She's a sweet cat with the cutest meow. I hope one day she'll actually let me pet her.
She looks very relaxed in that picture!
