Once Upon a Rainbow ... In the beginning, God created the world, and made Man and Woman. When Man takes Woman to meet the animals, a horse offers to carry her on his back, and Man asks God to bestow a gift on the kind and humble creature ... But when sin enters the world and the horse's gift is misused, trouble comes in all colors ... Based on a bedtime story in C. S. Johnson's Christian fantasy romance series, The Realms Beyond the Rainbow, The Legend of the Rainbow Unicorn: Or, How the Horse Became a Unicorn is a gorgeously illustrated tale featuring the work of artist Levi Tonin.
