This is Ellis Brayson, recently turned 30 and one half of a dating premade.
Originally from London, she came to New York with big dreams and ended up homeless for a while after a very bad breakup. While trying to pull herself back together she started writing sort of a tongue-in-cheek book about romance. She started posting bits of it online and got a publishing offer and it turned into an amazing best seller. It was only a one time thing, she just never had a second book in her, but in the meantime it launched her career as an advice and lifestyle columnist. I'm not sure yet if it's with a paper or a magazine.
Now she lives in Manhattan and is one of those women who's always working. Even if she's just getting groceries she's got a Moleskin out, scribbling notes on couples she stumbles across. She also writes a bit of lifestyle stuff so she attends the occasional party or event. She's a little critical of men, because of said breakup mentioned above, and she's got a fairly sharp tell-it-like-it-is tongue, although she can be genuinely sweet. She's easy to get along with and doesn't really care for being alone.
She needs everything except the ex and the boyfriend (both are the same guy and will be coming along shortly). I figure she didn't date much after the breakup, made one other ex, but she'd have been around the city to have made a few good friends, maybe she's got some family around? Part of her bio is in her journal. I'm still working on her a bit.
