Planesrunner is a 2011 young adult science fiction novel by British author Ian McDonald, and the first installment of the Everness series.

The book follows British teenager Everett Singh as he travels between alternate universes in search of his missing theoretical physicist father.

Hired as Sixsmyth's chef, Everett enlists Sen to infiltrate Charlotte's headquarters, the Tyrone Tower, to determine where Tejendra is being held.

She and her team are rebuffed by a mob, and the Everness leaves for the Goodwin Sands, where Sixsmyth has been challenged to an airship duel by one of her enemies, the arrogant matriarch Ma Bromley.

The Everness crew break into the Tyrone Tower on zip-lines and the Singhs are reunited, but Charlotte arrives with her jumpgun and demands the Infundibulum.

[2] Writing for The Telegraph, Anna Lisinski praised the detail with which McDonald describes E3, including the theme that prejudice is an ever-present potentiality in any culture, no matter its development.

[3] Susan Carpenter of the Los Angeles Times wrote that Planesrunner is "not just for kids", calling it thought-provoking and "a visually, if densely, written tale of sci-fi suspense that ponders big questions with wonderment and heart.

"[4] Stefan Raets of Tor.com agreed that the novel has "a lot to offer" non-young adult readers, complimenting the engaging characters and calling the setting of E3 "so insanely cool that it just about blows any other steampunk London clean out of the water."

[9] While the Everness crew assess their location and the condition of the airship, Everett tries to figure out how to interface the Infundibulum with Charlotte's jumpgun so he can choose the destination planes of future jumps.

Kept secret from the majority of people on Earth for 20 years, the Thryn Sentiency helped mankind achieve important medical and technological advancements, including the creation of the Heisenberg Gate.

The Thryn avatar Madam Moon rebuilds Everett's wrecked body with technology that provides enhanced strength, speed, and agility; heightened senses; and built-in weaponry.

Sixsmyth and the crew are taken into custody by the government force protecting the few survivors in London, led by a politician called the Agister of Caiaophas and her military commander, the Brigadier.

E10 Everett meets the E1 Tejendra, who guides a strike team to the Nahn-infested remains of Imperial University in search of a device used in a 1969 E1 survey to map thousands of planes.

Tejendra is assimilated during their frantic escape back to the Everness with the device, and Everett opens a Heisenberg Gate tuned to the center of a sun that incinerates the whole of the university and the Nahn.

She leads a strike squad into the airship expecting to face only the crew, but the Genequeen clade of Jiju attack the Everness as well, forcing Charlotte to flee and leave her team to be massacred.

After copying the Infundibulum, the Empress uses it to begin an invasion of billions of planes in the extended multiverse, and prompts the Worldwheel's sun to go nova, sanitizing the world and exterminating all of the other clades.

With Kaz's help, the airship crew infiltrates the Empress's city-ship over E10 London, and Everett sends a signal that jumps all of the Jiju ships into random planes, and then erases all copies of the Infundibulum.
