While Pendragon is trapped on Ibara, Alder returns to Denduron and reluctantly goes into battle again, and other Travelers face obstacles of various sorts, Saint Dane gains the power he seeks on Second Earth and makes his push to destroy and rebuild Halla.
With more questions than answers about Saint Dane, Bobby travels to the territory of Quillan and is forced to play games where only the winner survives.
They came from the sky parachuting out of military helicopters to invade Tucker Pierce's idyllic hometown on Pemberwick Island, Maine. They call themselves SYLO and they are a secret branch of the U.S. Navy. SYLO's commander, Captain Granger, informs Pemberwick residents that the island has been hit by a lethal virus and must be quarantined. Now Pemberwick is cut off from the outside world. Tucker believes there's more to SYLO's story. He was on the sidelines when the high school running back dropped dead with no warning. He saw the bizarre midnight explosion over the ocean, and the mysterious singing aircraft that travel like shadows through the night sky. He tasted the Ruby -- and experienced the powers it gave him -- for himself. What all this means, SYLO isn't saying. Only Tucker holds the clues that can solve this deadly mystery. Look to the sky because Pemberwick Island is only the first stop.
Once again, Tucker Pierce and friends must fight for their lives against the better-equipped SYLO, and they will risk nearly everything to keep each other safe the battle's climax nears.
Having escaped from Pemberwick Island, Kent, Tori, Olivia, and Tucker continue to try to get word out about SYLO, the organization that had quarantined them, while trying to avoid being caught in the middle of an inexplicable new civil war.

Ten territories co-exist across time and space, each with its own unique culture and all are doomed unless the Travelers and their leader, Bobby Pendragon, can protect their home territory from Saint Dane.
