Nancy Bailey is an animal behaviorist and author who lives in Michigan. She is most noted for her book Clifford of Drummond Island, a true story of the author and her amazing horse companion. Clifford is an intelligent Morgan horse who Nancy taught to dance, play with toys and even paint. She travels around the country with Clifford doing shows at expos, nursing homes, schools and libraries. Clifford serves as a source of inspiration for her works. Her interest in animal behavior started as a young girl when she taught her Labrador retriever to jump through a hoop and climb a ladder. Nancy is a self-taught trainer and acquired her skills from simply observing animal behavior. When not spending time with her animals, Nancy enjoys painting. Her work is inspired by her appreciation and love of nature. She creates many of the illustrations in her books.

Aka Geoffrey Caine, Glenn Hale, Evan Kingsbury, Stephen Robertson Master of suspense and bone-chilling terror, Robert W. Walker, BS and MS in English Education, Northwestern University, has penned 44 novels and has taught language and writing for over 25 years. Showing no signs of slowing down, he is currently juggling not one but three new series ideas, and has completed a film script and a TV treatment. Having grown up in Chicago and having been born in the shadow of the Shiloh battlefield, near Corinth, Mississippi, Walker has two writing traditions to uphold—the Windy City one and the Southern one—all of which makes him uniquely suited to write City for Ransom and its sequels, Shadows in White City and City of the Absent. His Dead On will be published in July 2009. Walker is currently working on a new romantic-suspense-historical-mainstream novel, titled Children of Salem. In 2003 and 2004 Walker saw an unprecedented seven novels released on the "unsuspecting public," as he puts it. Final Edge, Grave Instinct, and Absolute Instinct were published in 2004.
