At the same time, Walter and Ashley, with help from Joran and Selah, two Listeners from ancient times, try to open the portal that swallowed Matt. All the while they are searching for clues to cure a mysterious disease that threatens to kill the original anthrozils, including Jared, who was once the great Clefspeare.Both journeys are fraught with peril as LauÂren and Matt are thrust into Second Eden where a volcano, Mount Elijah, has erupted and devastated the land, killing many of the residents.

There is one person in his life for whom he still holds bitterness, and they are thrown together at the end of the story as a setup for the next.Lauren learns that the greatest of sacrifices is necessary to bring about the disease"s cure. Since she is the only one who believes the cure to be possible, she begins the path to sacrifice herself in order to save victims of the disease.
