LISHA CAUTHEN lives in Kansas City at the other end of the Santa Fe Trail--she can see it from the attic in her 100-year-old house. She doesn't mind the phantom footsteps she hears at night, but she does get irritated when someone invisible blows on her neck. She is an editor and writes children's books including You Are Here, a nonfiction picture book about space. You can learn more about Lisha at www.lishacauthen.com .
