The Soldiers of Halla
D.J. MacHale
 The Soldiers of Halla begins with the eleven Travelers, meeting in a crumbling wasteland of a city. They are immediately attacked by a helicopter, forcing them to seek refuge in the buildings. Bobby and Loor are trapped in a pit and watch as a colony of people are caught by the helicopters in a nearby building. When the helicopters leave, however, the Travelers gather back together. The first generation of Travelers quickly appear, such as Osa, Loor's mother, and Seegen, Kasha's father, and lead the other Travelers away. Bobby is met by his family again, who tell him that the wastleand was in fact the New York City zoo on Third Earth. His family leads Bobby to another place, that is filled with dark clouds and crumbling, gray earth. They confess that they know all that has transpired in Halla so far, including Bobby's murder of Alexander Naymeer on Second Earth. Moreover, they tell him that Solara is indeed the essence of Halla and thus the ten territories. Each victory and defeat inflicted by the Travelers and Saint Dane is reflected in the overall health of Solara. All of the souls of Halla are transferred to Solara after they pass on in Halla. As the exiles are in Eelong and the klees(cats that are the senitent species of the jungle like territory of Eelong) are going to attack them and the gars(humans that are not quite as intelligent as the klees.)The travelers defeat them and the travelers go back to Solara. Uncle Press then proposes that they should protect the exiles as they are the only positive energy that keeps Solara running. Bobby proposes that Uncle Press's plan would only delay defeat. He thinks they should make a portal and transport the travelers to the Ravinians and defeat them. Bobby gets into a fight with Saint Dane, and as he uses up all of his power, the foe dies. As the Travelers are victorious, all of Halla is saved from a fatal disaster.
