A fascination with animal behaviour has led writer and photographer Julia Soplop around the globe. So, naturally, when her daughters started riding lessons, the horses' behaviour immediately drew Soplop in. What began as a casual interest rapidly escalated into amassing a collection of horse literature; dashing around the country to photograph wild horses; and, ultimately, writing this book. Soplop's work has appeared in numerous publications, including National Geographic Magazine Online, Design Mom, Skiing, and the Summit Daily News. She is also the author of Documenting Your World Through Photography. She has a B.A. in French from Duke University and an M.A. in Medical Journalism from the University of North Carolina at Chapel Hill. She lives with her family outside of Chapel Hill.
