Song of the Wanderer

In the second book of the Unicorn Chronicles by Bruce Coville, 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, and to the back of the dragon Ebillan's cave. Only there will she find the gate that can bring her back home.

As Cara embarks on the journey of her life, there is one person who stands in her way: Beloved, Cara's ancient ancestor, who has spent a lifetime dedicated to ridding the earth of unicorns.
