"A Pynchonesque mega-novel that periodically calls to mind the films ofInceptionandThe Matrix.... What a ride!" --The Washington Post

>When suspected dissident Diana Hunter dies in government custody, it marks the first time a citizen has been killed during an interrogation. The System doesn't make mistakes, but something isn't right about the circumstances surrounding Hunter's death. Mielikki Neith, a trusted state inspector and a true believer in the System, is assigned to find out what went wrong. Immersing herself in neural recordings of the interrogation, what she finds isn't Hunter but rather a panorama of characters within Hunter's psyche: a lovelorn financier in Athens who has a mystical experience with a shark; a brilliant alchemist in ancient Carthage confronting the unexpected outcome of her invention; an expat Ethiopian painter in London designing a controversial new video game, and a sociopathic disembodied intelligence from the distant future.

Embedded in the memories of these impossible lives lies a code which Neith must decipher to find out what Hunter is hiding. In the static between these stories, Neith begins to catch glimpses of the real Diana Hunter--and, alarmingly, of herself. The staggering consequences of what she finds will reverberate throughout the world.

A dazzling, panoramic achievement, and Nick Harkaway's most brilliant work to date,Gnomonis peerless and profound, captivating and irreverent, as it pierces through strata of reality and consciousness, and illuminates how to set a mind free. It is a truly accomplished novel from a mind possessing a matchless wit infused with a deep humanity.
