It's important to not marginalize any people group in fiction. A complete, authentic-feeling world should include many different elements of life and culture. For this reason, my books will almost always contain people of faith.
I was a teenage girl once. I was not an overweight teenage girl, but I had really bad acne when I was 11 or 12 years old. It was heart-rending, and people made fun of me. People whispered when I walked by in the hallways, and I was sure they were whispering about me. My adult perspective is maybe they weren't.
I was a Social Science major in college, with an emphasis in secondary education. I took as many courses on the American colonial era and westward expansion as I could. This turned out to be wonderful preparation for writing fantasy novels.
I have tremendous respect for teens who navigate the quagmire that is modern religion. If there is any message in my books, I want it to be that it's okay to ask questions, and it's okay to come up with a belief system all your own. Teens who change their worldviews in the face of tremendous social pressure are heroes to me.
When you write about faith, people will be upset with you no matter what. I've heard from readers who were disgusted with the depiction of monotheistic religion. I've also heard from readers who were upset because my portrayal of faith did not adhere to their specific doctrines. Fortunately, I have high risk tolerance.
I saw 'Star Wars' for the first time when I was four years old. Sure, I thought Princess Leia was awesome. But the character I identified with most was Luke Skywalker. I left the theater certain the Force was strong with me, that I could train to be a Jedi and wield a lightsaber just like Luke.
