Bolder is his by birth – beautiful and golden, the success of his father and grandfather flowing in his veins. Flint, sired by another stallion, is the colt Cloud raised. Now, Bolder has gathered some mares of his own, while Flint has joined a group of bachelor stallions, young guns roaming the mountains. Who will rise to challenge the mighty Cloud? Will nature or nurture produce the next great stallion of the Arrowheads?
