Terri Farley has always loved horses and is overjoyed that she outgrew her childhood allergy to them. She taught middle school and high school language arts and journalism in inner-city Los Angeles before moving to the cowgirl state of Nevada. Now she rides the range researching the books that have made her an award-winning author and an advocate for the West's wild places and wildlife--especially wild horses. Through school and library visits, Terri continues to work with young people learning to make their voices heard. She lives in a one-hundred-year-old house with her family, which includes her dog, Willow. In true collie fashion, Willow rescued the youngest member of the Farley family, an orphaned kitten named Tamarack. Kirbi Fagan and her husband live in Milford, Michigan, where they practice sustainable gardening on their small homestead. She's the illustrator of the picture books We Are the Scrappy Ones by Rebekah Taussig and Summer of the Tree Army by Gloria Whelan as well as the New York Times bestselling novel A Horse Named Sky by Rosanne Parry.

The first picture book she both wrote and illustrated is The Big Empty about the sagebrush ecosystem. Find more of her work online at KirbiFagan.com.
