I've started writing a new series—this time urban fantasy, which is new for me. I've recently realized that the first novel in the series will only be about 44,000-55,000 words. Do you think this can work? I understand that book length is determined by the story—and I agree with that. But would I be going against the expectations of urban fantasy readers? I've started reading more urban fantasy myself, but haven't yet read enough to develop a strong opinion on this.
