Once every hundred years, a black foal is born, prophesied to either unite or destroy the five herds of flying horses that live in Anok—fated to become the most powerful pegasus in all of the land.

Star is this black foal.

Even though Star has malformed wings that make him unable to fly, the leaders of each herd will take no risks and want to execute Star before his first birthday. With the help of his friends, Star must escape the clutches of the powerful leaders, and his epic journey of self-discovery turns into a battle between good and evil that will keep readers eagerly turning the pages.

When Star received his powers on his first birthday, he became the most powerful pegasus in Anok. However, many were afraid to follow him and felt safer staying with their over-stallions. The rest unified with Star and formed River Herd.

But now a horrible plague threatens the five herds, and the heartless over-stallion Rockwing of the Mountain Herd has plans to kidnap Morningleaf, Star's closest companion, and take back Sky Meadow. Star begins to question his ability to keep his herd safe, especially with the threat of Nightwing the Destroyer's return—the pegasus who inherited the starfire before Star and used it for evil. As much as Star wants to rely on his friends again for support, he's afraid of the starfire he's inherited. Star can heal, but he can also destroy. And the question is: Will his dark powers overcome him?

It has been many moons since Star received his starfire power. He has gone from being born a dud—unable to fly and shunned by the five herds of Anok, including his own—to becoming a strong yearling, ready to lead his own herd as an over-stallion. But now he will face his toughest challenge yet. Nightwing the Destroyer, Star’s eternal rival, is amassing an army to destroy him and all of Anok. The only way for Star to defeat him is to learn how to fight like a warrior—without using his starfire. For if he uses his power, even to heal, Nightwing will know where to find him.


As the threat of war looms over Star’s head, he can’t help but wonder if the current peace among the united pegasi is strong enough to defeat the powerful Destroyer once and for all.
