Kali Wallace, for most of her life, was going to be a scientist when she grew up. She studied geology in college, partly because she could get course credit for hiking and camping, and eventually earned a PhD in geophysics researching earthquakes in India and the Himalayas. Only after she had her shiny new doctorate in hand did she admit that she loved inventing imaginary worlds as much as she liked exploring the real one. She s from Colorado but now lives in Southern California. You can find her at www.kaliwallace.com and on Twitter @kaliphyte.
