If I read the first couple pages, or even sometimes more, my suspicions were correct almost 100% of the time -- the world building is flawed.
Well, you might ask, what the hell is world building? Editor Keith Kahla once told me world building wasn't just the room, it was the furniture and the art. He didn't mean that specifically, he meant it as a metaphor. It's not just what's there, it's what gives the place character. It's the scars and distinguishing marks and the mannerisms. It's the smell of a place. It's the layers and nuances of the setting.
Still not clear?
Well, often times the best way to see what something is, is to see a good example.
Here are the six books that the Romantic Times nominated for Best Urban Fantasy world building for 2013.
