As a child, a local librarian gifted me with some books on horses, many of which were from the 1950s and 1960s: titles like Black Gold, Misty of Chincoteague, and nonfiction books on horses soon graced my room’s shelves. Included in this stack was a plain brown book with the drawing of a horse’s head: Old Bones, the Wonder Horse by Mildred Mastin Pace. Long before I would sit down to write about another wonder horse, I read about the tall, lanky gelding that wowed crowds for ninety-nine starts, the heart-shaped blaze on his forehead an enduring symbol of a beloved thoroughbred. And, nearly thirty years later, I got to read about him again in Here Comes Exterminator! by Eliza McGraw.
