The fifth book in the popular Morgan Horse series introduces a new horse, Annie. Uncertain of her origin, Chauncy decides to bring Annie home to Gallant Morgans, but he makes it clear she can only stay if he can locate her registration papers. When Heather discovers Annie's true identity, she is afraid to tell Chauncy, knowing the horse may be returned to a cruel trainer. Will Chauncy send Annie back to her original owner? What will happen to Annie if she is returned? Heather hides the truth from her friend and soon events spiral out of control. In addition to the mystery, this book also includes the exciting Justin Morgan class, the famous class that re-enacts the amazing athletic feats of Justin Morgan, and the Morgan Trotting Races, held on the same dirt road that Justin Morgan raced over 200 years ago. Both events are treasured by Morgan Horse enthusiasts around the country. Winner of two national book awards! Annie is a Moonbeam Children's Book Award winner, plus a Reader Views Literary Award winner!
