Cara must return to Earth to save her grandmother, the Wanderer. But to do so, Cara must first travel through the wilderness of Luster, land of the unicorns, full of unknown creatures and perilous adventure around every bend in the road. Only at the back of the dragon Ebillan's cave will she find the gate that can return her to Earth.
Embarking on the journey of her life, Cara will face vicious terrain, delver attacks, and a surly dragon. Beyond all this looms one more danger: Beloved, Cara's infamous ancestor, who has dedicated a lifetime to ridding the earth of unicorns. Is Cara strong enough to resist Beloved's ruthless magic and trickery? Can she bear betraying her own blood?
