Hi Eric - Mostly from conversations and overheard conversations with friends. For instance, I passed through Vegas a couple years ago and had dinner with a group of men who'd been in the military with me. One of them was recently divorced with a ten-year-old daughter, and I overheard him say how tough dating was when you had kids. The other man told him to just wait until the girl turned 13 - "There's nothing more judgmental than a thirteen-year-old daddy's girl. Every woman I bring around is too fat, too thin, too tall, dresses badly, has crappy hair, no taste, and everything else the little brat can think of." I immediately wondered what would happen if he brought home someone 5-7 years older and the kid said something ugly to the woman, dad and daughter have a fight and the kid takes off. If that kid got in some type of trouble and the only one who could save her was that woman - what would that be like for both of them. Just like that, I knew I had a book, and Saving Emily was born. Most of my books are based on a question like that. Thank you for asking.
