Everything comes to a head in this seventh book in the New York Times best-selling series.

The world of Erdas will be changed forever. Conor, Abeke, Meilin, and Rollan were once ordinary kids. Then they discovered that they had spirit animals - wise and powerful partners who granted them with amazing gifts...and a legendary responsibility. Together the team has journeyed across Erdas, racing to stop a merciless foe. They have laughed and fought together. They've won challenges and lost friends. Some have even lost themselves.

Now that journey is about to end. They must reach a place forgotten by time and face off against an ancient enemy breaking free from his prison. They have just one chance to stop him...or the whole world will shatter.
