Here an extract from Rise of Nine, chapter 1:
I remember feeling my face burn with embarrassment. Her challenge hit its mark. I finally said, ‘No, I’ve never been on an airplane.’ I wanted to tell her I’ve been on something much bigger, something much more impressive than a little airplane. I wanted her to know I came to Earth on a ship from another planet called Lorien and the trip had covered more than 100 million miles. I didn’t, though, because I knew I had to keep Lorien secret.
100 million miles is as much as the distance between Earth and the Sun. Lorien is located in another star system. How is it possible that they travelled such a short distance?
