That's not very original, but Ethsharites aren't much on originality. You don't give your three largest cities the same name if you want to be original. The world of Ethshar is the setting for several novels and short stories, with more planned. Each of these stories is designed to stand on its own, so that a reader who picks up any one of them can understand and enjoy it, and may well not even realize it's part of a series.
Some stories stand alone better than others.
I am forced to admit that The Spell of the Black Dagger is probably not the best place to start, as it includes appearances by several previously-established characters. In particular, it helps to have read With A Single Spell before tackling it. I think all the others should work fine as starting points. I don't want to mislead anyone. The Ethshar stories are fantasy, but they don't quite fit in the usual niches in that field.
