A GUARDIAN BOOK OF THE YEAR
'Gnomon is an extraordinary novel, and one I can’t stop thinking about some weeks after I read it. It is deeply troubling, magnificently strange, and an exhilarating read.' Emily St. John Mandel, author of Station Eleven
‘The best thing he’s ever written … It is an astonishing piece of construction, complex and witty … It is a magnificent achievement … He’s never written a bad book, but this is the one that’ll see him mentioned in the same breath as William Gibson and David Mitchell … This book seriously just destroyed me with joy.’ Warren Ellis
‘Nick Harkaway: bonkers, brilliant and hilarious … Effervescent, clever and entirely fantastic.’ Sunday Times
‘[Harkaway] is the missing, but somehow logical, link between David Mitchell and Terry Pratchett.’ Independent
Near-future Britain is not just a nation under surveillance but one built on it: a radical experiment in personal transparency and ambient direct democracy. Every action is seen, every word is recorded.
Diana Hunter is a refusenik, a has-been cult novelist who lives in a house with its own Faraday cage: no electronic signals can enter or leave. She runs a lending library and conducts business by barter. She is off the grid in a society where the grid is everything. Denounced, arrested and interrogated by a machine that reads your life history from your brain, she dies in custody.
Mielikki Neith is the investigator charged with discovering how this tragedy occurred. Neith is Hunter’s opposite. She is a woman in her prime, a stalwart advocate of the System. It is the most democratic of governments, and Neith will protect it with her life.
When Neith opens the record of the interrogation, she finds not Hunter’s mind but four others, none of which can possibly be there: the banker Constantine Kyriakos, pursued by a ghostly shark that eats corporations; the alchemist Athenais Karthagonensis, jilted lover of St Augustine of Hippo and mother to his dead son, kidnapped and required to perform a miracle; Berihun Bekele, artist and grandfather, who must escape an arson fire by walking through walls – if only he can remember how; and Gnomon, a sociopathic human intelligence from a distant future, falling backwards in time to conduct four assassinations.
Aided – or perhaps opposed – by the pale and paradoxical Regno Lönnrot, Neith must work her way through the puzzles of her case and find the meaning of these impossible lives. Hunter has left her a message, but is it one she should heed, or a lie to lead her into catastrophe? And as the stories combine and the secrets and encryptions of Gnomon are revealed, the question becomes the most fundamental of all: who will live, and who will die?

“So the thing I said that she said she couldn’t advise on: that’s the thing she would advise if it wasn’t outside her professional competence. See? That’s what she thinks we ought to do. Blow it all wide open. But she can’t say that with squit in the room or they’ll say she advised us to break the law or whatever and take away her funny hat.”
“She’s a solicitor,” Annie said primly.
“Whatever. That’s what she’s telling us to do.”
“I thought she was telling us not to do that.”
“Yeah. Squit probably thinks so, too. Fuck him.”
“You’re getting all this from what she said about Turnpike?”
“Basically. It was a bit of a red flag. What, it really doesn’t mean anything at all to you? Still?”
“Colson,” Annie said. “You’re an info-rat. Not everyone’s brain works that way. The merger of state and corporate power: why is it important?”
Colson scowled as if both the question and the answer were part of some conspiracy of which he particularly disapproved. “It’s one of the basic victory conditions of Italian Fascism,” he said.
The bookshop is closed, but [the proprietor] goes down to the back office, puts on the kettle and opens the door. People will be very alarmed, and in his experience they always feel better knowing there's a bookshop open.
They say "dysfunctional," but all I hear is "uppity."

composition is collision, synthetic as much as original. Authors are accretors. (292)
Most successful book: The Mad Cartographer’s Garden, in which the reader is invited to untangle not only the puzzle that confronts the protagonists but also a separate one allegedly hidden in the text like a sort of enormous crossword clue... (6)FA LA JI RO JI JA is repeated often enough to make me want to start cracking.
There are many advantages to the end of privacy, and one of them is the obsolescence of social awkwardness. The Inspector finds this outcome both efficient and laudable. (28)Characters are a treat to dive into, from the braggadocio-drenched, shark-haunted Greek banker to the sinister alien intelligences. There's also Harkaway's deep geekery, which lets him toss off references to "extremely rare and undervalued duodecimal quipus" and "locatively discursive spimes."
Finance by itself is ruthless, and that ruthlessness is its salvation. The real disasters are only possible when you bring politics into it, because politics is about pretending to care.(65)
Well. You don’t murder a universe without some degree of discomfort.(541)
