"Planesrunner is chock-full of awesome. Ian McDonald's steampunk London blazes on a vast scale with eye-popping towers, gritty streets, and larger-than-life characters who aren't afraid to fight for each other. The kind of airship-dueling, guns-blazing fantasy that makes me wish I could pop through to the next reality over, join the Airish, and take to the skie.s"
-Paolo Bacigalupi, Ship Breaker 

"What joy to find science fiction based on real scientific concepts... In his debut for teens, established science-fiction writer McDonald builds a world just different enough to charm readers into believing... Shining imagination, pulsing suspense and sparkling writing make this one stand out."
-Kirkus Reviews, Starred Review  

"McDonald writes with scientific and literary sophistication, as well as a wicked sense of humor. Add nonstop action, eccentric characters, and expert universe building, and this first volume of the Everness series is a winner."- Publishers Weekly, Starred Review

"Smashing adventure fiction that spans the multiverse without ever losing its cool or its sense of style. Ian McDonald is one of the greats of science fiction and his young adult debut is everything you could hope for: romantic, action-packed, wildly imaginative, and full of heart."- Cory Doctorow, For the Win

"[I]t's world is as sharply imagined and inventive as we've come to expect from McDonald. And it also may be the first steam-free steampunk novel... first-rate adventure writing... by the cliffhanger ending we're ready to follow [Everett] into whatever new universes McDonald can concoct, and the next one already looks interesting. Planesrunner is not only excellent YA SF in terms of its likeable characters and well-executed setpieces, but is simply good SF ina way which almost reinvents, and possibly makes addictive, the old parallel universe trope. It's fun."- Locus 

There is not one you. There are many yous. There is not one world. There are many worlds. Ours is one among billions of parallel earths.

When Everett Singh's scientist father is kidnapped from the streets of London, he leaves young Everett a mysterious app on his computer. Suddenly, this teenager has become the owner of the most valuable object in the multiverse-the Infundibulum-the map of all the parallel earths, and there are dark forces in the Ten Known Worlds who will stop at nothing to get it. They've got power, authority, the might of ten planets-some of them more technologically advanced than our Earth-at their fingertips. He's got wits, intelligence, and a knack for Indian cooking.

To keep the Infundibulum safe, Everett must trick his way through the Heisenberg Gate that his dad helped build and go on the run in a parallel Earth. But to rescue his dad from Charlotte Villiers and the sinister Order, this Planesrunner's going to need friends. Friends like Captain Anastasia Sixsmyth, her adopted daughter, Sen, and the crew of the airship Everness.
