Phil Tucker, author of The Chronicles of the Black Gate (it's great, try it), has a pretty similar story to mine. He'd written a few books prior to Black Gate, but that series is the one that really took off for him. It came out right around the time Benjamin Ashwood did. I saw he has a great blog post up today with some advice for people getting into the self-published author game. It's the kind of post I tell myself I will write, but, at least for today, it's easier to just steer you to Phil.
