A lot of people feel like urban fantasy is a shortcut that gets you around world-building, because it's set "in the real world." But it doesn't really work that way, as I found out. You have to come up with just as consistent an internal cosmology and magic system as you would if you were writing high fantasy.

If people ever look down upon you for crying for fictional characters, you should give them a gentle, pitying look and feel bad for them. If they've never cried for a fictional character, then they've never loved one (and what a joy that is). If they've never cried at a book, a movie, a piece of music, then they've missed one of the great pleasures life has to offer. Just because fiction does not contain things that are real doesn't mean it doesn't contain truth, and we find it through the alchemy of our tears.

For such a long time, when you're a writer, you really are just writing for yourself, and maybe a few friends. So it's really amazing when your book gets out there and more people are reading and responding to it. It really makes the world of the books feel real.

The great thing about writing for a younger audience is that they will give it to you straight with their responses. They'll tell you exactly what they liked and didn't like, and when they're enthusiastic, they're unashamedly enthusiastic. They'll talk to you about your characters as if they were real people, which is wonderful.

I believe that authors don't have a responsibility to include "messages" in their work, but they do have a responsibility to write a world that seems true and real, never more than when expecting readers to believe in magic and angels and fairies.

It didn’t matter, anyway. There was only one thing she could ask for, in the end, only one real choice. She raised her eyes to the Angel’s. "Jace," she said.
