As a dark force engulfs the land, the fate of Erdas has fallen on the shoulders of four young strangers who each have forged a rare bond with their spirit beasts--a bond that gives great powers to all of them.

Continues the adventures of Conor, Abeke, Meilin, and Rollan and their spirit animals as they continue their efforts to protect Erdas from dark forces.

When an ancient dark force emerges from a centuries-long slumber, Conor, Abeke, Meilin, and Rollan must stop it from sweeping through Erdas and destroying their spirit animals--and the world.

As tensions rise, they must stay close together and patrol the DC streets at night, seeking signs of the Harbinger, an entity that is killing Wardens and demons with no seeming rhyme or reason. Forbidden to be with each other, Zayne and Trinity fight their feelings and turn to unusual sources for help -- the demon Roth and his cohorts. But as deaths pile up and they uncover a sinister plot involving the local high school and endangering someone dear...

As the Conquerors try to destroy Erdas, Meilin -- fed up with waiting and ready to fight -- sets off into enemy territory with her spirit animal, a panda named Jhi. Her friends Conor and Abeke aren't far behind ... but they're not the only ones.

With some convinced the Greencloaks are to blame for recent destruction, Conor, Abeke, Meilin, and Rollan find themselves on trial and later on the run when a Greencloak attacks the council of world leaders from within its ranks.

Framed for a crime they didn't commit, four fugitives travel the deserts of Nilo looking for a secret library that houses the wisdom of Erdas and is guarded by their old friends.
