"As we rode through the dark, I realized that the sounds of her hooves hitting the ground had slowly faded. I looked down and saw that the ground was getting farther and farther away. I let go of Angel's neck, sat up on her back, and looked out around us. Protruding from each of her sides, were huge, beautiful, feathered white wings."

Harley spent most of her time with her horse, Angel, riding through the fields behind their home. Her late mother shared Harley's love for horses and adventure. Spending time with the horses was her way of spending time with her mom.

One night while out riding with her best friend, they discovered that their horses had developed an extraordinary ability, nothing like they had ever seen. They were led to a secret Realm where they learned they were not alone. Many horses from around the world had gone through a change and were gathered here with their riders.

In the Realm, Harley learned that they were not here by chance. They had been chosen to compete in the Race for the Realm. In the Race she would face life threatening situations, monstrous creatures, and a merciless group of mercenaries with one goal - to capture and use the horses for their own gain and power. Now Harley must make the decision whether she will leave her horse behind and return home or join the Race and prove that she is worthy to become a Protector of the Realm.
