When Star received his powers on his first birthday, he became the most powerful pegasus in Anok. But many were afraid to follow the yearling colt and felt safer remaining with their over-stallions. The rest unified with Star and formed River Herd. Now his new herd is homeless and menaced by predators, causing Star to question his ability to keep them safe.

And then the Blue Tongue plague appears, quickly sweeping through the north and leaving destruction in its wake. Meanwhile, Mountain Herd is outgrowing its territory, and its over-stallion, Rockwing, hatches a plan to kidnap Morningleaf and take back Sky Meadow, a place Star has vowed never to return. But with all this happening, a greater threat has shaken Star to his core. Nightwing the Destroyer is alive, and his rise to power threatens all of Anok.

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 he can't help but question his purpose: Is he truly the one to unite the herds? Or will his dark powers overcome him?

Jennifer Lynn Alvarez captivates readers with the dramatic and action-packed continuation of Star's story—a tale readers won't want to put down.
