Willow Star: Beyond Home

Willow Star: A peaceful world for eons until an ancient evil is reawakened.
And the only ones who can stop it are four teenagers.
The fate of the divided world now rests on their shoulders, and they alone hold the keys to the saving or destruction of their world, forming a line of heroes known to their people as Guardians. Each from different backgrounds and lands, they are nothing alike, possessing only one common ground: great power.
In a race against time, a rebellious schoolgirl, an ordinary boy, a forgotten princess, and a scrappy orphan unite to deliver their world before the evil reduces it to rubble, and there is no world left to save.
