Just like the previous two Legends books, this one also profiles a number of stallions and several mares who gained fame in the American Quarter Horse Association. While some of them played roles in the formation of the breed, others are more contemporary. Some gained fame on the track, while others carved their niches in the show ring, and some did both. Many are also household names in the Quarter Horse industry because of their additional impact on the breed as sires and dams.

Each chapter is about a specific stallion or mare, and includes a four-generation pedigree, a summary of the horse's performance record and sire or production record, and many photographs.
