The Merchant of Death (pendragon, #1)

The first installment in D.J. MacHale's Pendragon series follows Bobby Pendragon, a fourteen-year-old from Stony Brook, Connecticut, whose ordinary life is upended when he discovers he is part of an interdimensional group called the Travelers, charged with protecting the universe from chaos.

Bobby's story begins on the night of a county semifinal basketball game. Courtney Chetwynde, a classmate who has had a crush on Bobby since fourth grade, arrives at his front door and confesses her feelings. They share their first kiss, only to be interrupted by Bobby's Uncle Press, a mysterious man whose background Bobby's mother avoids discussing. Uncle Press is uncharacteristically tense and asks Bobby to leave with him immediately, saying people need their help. Bobby reluctantly abandons the game and his normal life.

Uncle Press drives Bobby into a dangerous section of the Bronx and leads him into an abandoned subway station. A man in a police uniform confronts them, but Uncle Press recognizes the man as Saint Dane, the series' primary antagonist. Saint Dane uses a hypnotic stare to force a homeless man to leap in front of a subway train, then transforms into his true form: a seven-foot-tall, pale figure with icy blue eyes. A gun battle erupts, giving Bobby time to flee along the tracks. Chased by ferocious dog-like creatures called "quigs," Bobby finds a door marked with a star and shouts the password "Denduron." The door opens onto a glowing, crystal-walled tunnel called a "flume," and Bobby is pulled through it across the universe.

The narrative alternates with events on "Second Earth," the Travelers' name for Bobby's home territory. Bobby's shy best friend, Mark Dimond, receives a ring from Osa, a Traveler and mother of a warrior named Loor, who appears in his bedroom at night. The next morning the ring activates, expanding and depositing a scroll of parchment through a dark portal. The scroll is Bobby's first journal. Mark shares the journal with Courtney, and together they discover that Bobby's house has vanished and all records of the Pendragon family have been erased.

Bobby emerges on a snowy mountaintop lit by three suns. Uncle Press arrives through the flume and explains that Denduron is a "territory" reached by traveling through space and time, and that Bobby is a "Traveler." They change into local clothing and attempt to sled past sleeping quigs, which on Denduron are massive bear-like beasts with bone spikes. Uncle Press kills one with a spear; the sled crashes in the forest, and mounted knights capture Uncle Press while Bobby loses consciousness.

Bobby wakes in a village hut, tended by Loor, a fierce young warrior, and Osa, both Travelers from the territory of Zadaa. Osa teaches Bobby about Denduron: The Milago are an enslaved mining tribe forced to dig for precious blue stones called "glaze," while the Bedoowan are a ruling warrior class living in a fortress carved into ocean bluffs under Queen Kagan. Bobby witnesses a Transfer ceremony, a quota-weighing ritual in which Saint Dane, disguised as Kagan's advisor "Mallos," ensures the miners cannot meet an impossible quota. A man is thrown alive into a mine shaft as punishment. Osa takes Bobby into the mines, revealing miners slowly dying from poisonous gas.

Bobby's attempt to flee goes wrong when he mistakes Alder, the Denduron Traveler and a Bedoowan knight, for an enemy and tackles Loor into a freezing river. Loor cannot swim, but Bobby uses lifeguard training to save them both. Alder reports that Uncle Press will be executed the following day. Loor condemns Bobby as selfish for planning his escape while his uncle faces death. Shortly after, Osa is killed by Bedoowan archers while defending Bobby. Before dying, she gives Bobby the Traveler ring and tells him that "Halla," the totality of existence across every territory and time, is in his hands.

Bobby resolves to rescue Uncle Press and writes to Mark requesting supplies, including a flashlight, walkie-talkies, a laser pointer, and a radio-controlled motorcycle. Loor reveals a second flume gate in the mines, and Bobby travels back to Second Earth, where Mark and Courtney meet him with the supplies. Bobby insists on returning, and his friends choose not to tell him about his family's disappearance, fearing the news would derail his rescue mission.

Back on Denduron, Bobby, Loor, and Alder infiltrate the Bedoowan palace through a secret mine passage, using Bobby's gadgets to create diversions. Uncle Press has been moved, however, and Alder, captured and threatened with Loor's death, is forced to lure Bobby into Queen Kagan's throne room, where all three are seized. Saint Dane tells Bobby that "Halla will fall." The captives are taken to a stadium atop the palace for execution, but when Uncle Press enters the arena, Bobby blows a silent dog whistle that cripples the attacking quig. The four Travelers escape, but Uncle Press is furious to learn Bobby brought items from Second Earth, violating the Traveler rule of using only what each territory provides.

In the forest, they discover Milago miners training with "tak," a naturally occurring explosive that detonates on impact, under the direction of Figgis, a one-eyed Milago merchant. Uncle Press warns that weaponizing tak will give one tribe unchecked destructive power, leading to endless war, which is exactly what Saint Dane wants. Rellin, the chief miner, captures the Travelers and reveals a massive tak bomb in an ore car, triggered by a battery salvaged from the flashlight Bobby brought from home. Bobby realizes with horror that he delivered the missing component. Uncle Press explains that Saint Dane manipulates territories toward chaos, and Denduron is the first "domino" in his plan to destroy Halla.

Rellin disguises the tak bomb as a gift of glaze and wheels it into the Bedoowan stadium. Saint Dane knowingly permits the bomb, wanting the tak used regardless of who wins. Bobby devises a counter-plan: He climbs into the quig pens, uses himself as bait, and has Loor release a quig into the stadium. In the chaos, Uncle Press pins Rellin's arm to the ore car with a thrown spear, preventing him from reaching the detonator, then hurls the small battery-detonator at a second quig, destroying it. The explosion serves as the signal Rellin had prearranged for the Milago army to charge the Bedoowan.

Bobby and Loor dissolve the remaining tak by pouring water into the ore car, exploiting tak's solubility. They chase Figgis into the mines, where cave-ins seal them in a cavern made entirely of tak. Figgis transforms into Saint Dane, revealing the real Figgis died years ago. Bobby refuses Saint Dane's offer to join him and ignites the tak dust in the cavern. Saint Dane flees through the flume to a territory called Cloral. Bobby carries the unconscious Loor to an ore car and rides it out a ventilation shaft into the ocean as the mine explodes underground.

The explosion destroys the Bedoowan palace, which collapses into the sea, but most people survive. Bobby and Loor climb the bluffs to find the two tribes wandering together, no longer fighting. Uncle Press mediates between Rellin and Queen Kagan about how to rebuild. With the palace gone and the tak eliminated, the tribes must cooperate.

Uncle Press takes Bobby home, where Bobby discovers the empty lot where his house stood. Uncle Press reveals that Bobby's family raised him to prepare him for the Traveler role and that their departure was always planned. Press is not Bobby's biological uncle, and Loor confirms she underwent the same experience with Osa. Bobby says goodbye to Mark and Courtney, and Uncle Press promises Bobby will see his family again. Loor returns to Zadaa for Osa's burial, while Bobby and Uncle Press prepare to pursue Saint Dane to Cloral. Months pass with no contact until the ring activates during a school day, delivering a journal written on waterproof green leaves: Bobby's first dispatch from Cloral. Mark and Courtney rush to read it together, setting up the next volume in the series.
