The Never War

The Never War is a book in the Pendragon series by D.J. MacHale. In this book, the main character, Robert "Bobby" Pendragon follows the antagonist, Saint Dane, to a territory called First Earth, which is essentially Earth in the year 1937.
Plot summary.
Bobby Pendragon and Vo Spader, the Traveler from Cloral, arrive on Veelox a few weeks after the death of Bobby's uncle, Press Tilton, only to figure out from Aja Killian, the Traveler from Veelox, that Saint Dane went to First Earth. They flume there (New York City, 1937) to be greeted by bullets from gangsters that Saint Dane has hired. They then met the First Earth Traveler, who saved them from the gangsters. He is a bell captain at the Manhattan Tower Hotel named Vincent Van Dyke, nicknamed "Gunny". Bobby and Spader become employed as bellhops there, and investigate the ties between First Earth's Turning Point, rival crime godfathers Max Rose and Winn Farrow, and the Nazi party.
The critical connection is revealed to be the "Hindenburg" zeppelin. To understand its significance, Bobby and Gunny visit Third Earth, in the 51st Century. The Traveler of Third Earth, Patrick, accesses a computer that predicts the future in which they save the "Hindenburg": industrial spies working for Max would lead to the Nazis developing an atomic bomb and disastrously winning World War Two.
Bobby and Gunny return to First Earth, only to find that Spader and Rose have gone ahead, seeking to stop Winn Farrow from shooting a firework rocket into "Hindenburg". Bobby was flown to the LZ-129's launch site by a female aeroplane pilot called Nancy Olsen (Jinx), who has been his friend and client at the hotel. Once parachuting from the aeroplane, Bobby tracks down Max and Spader, who are seconds from departing to meet Max's airship arrival. Bobby accompanies them, and with Third Earth foresight, manages to save the entire entourage's lives. While on Third Earth, the young Traveler learns that Max Rose was destined to die on the same highway, on the same day, after crashing into a motorcycle cop. With Max unconscious and Spader, convinced stopping the "Hindenburg" will save First Earth, heading for the airfield, Bobby uses Max's car to follow them. Spader, misunderstanding, tries to stop the rocket from launching; Gunny holds him back, but fails. Spader tries to save the "Hindenburg" on his own, but is stopped by Winn Farrow. Spader begs Bobby to save the "Hindenburg". Looking up, Bobby sees the faces of those who will die in the explosion and is reluctant to let them die. Gunny again intervenes, holding him until the rocket launches and the zeppelin burns.
After the whole incident is over, Bobby is upset that Spader's emotions nearly got the better of him which almost lead to the destruction on all three earth territories. Bobby tells Spader to return to Cloral until he learns to control his emotions.
Full of angst over his role in the tragedy, 
Bobby returns to his home on Second Earth (the 21st-century) 
for a pause in his Travels. After a week, he receives a call from Gunny, and meets him back at Bobby's old house a few hours later. Gunny arrives in a limousine with an elderly man claiming to know Bobby's great grandfather (unknowingly referring to Bobby when he was on First Earth), and explains how Uncle Press had died, describing how an accomplice (who the Gangster revealed to be Saint Dane) persuaded Tony, the gangster's partner, into shooting a Tommy Gun into the flume. He states clearly that he never fired a bullet. He then gives Bobby his Traveler ring which the gangster took from him on First Earth. Bobby thanks the gangster, and he and Gunny accompany the gangster down town to the flume. This is where "The Reality Bug" begins.
