Author Hari Kunzru has told the BBC that his follow-up to the award-winning The Impressionist is aimed at highlighting the effects of globalisation - through a computer virus.
Kunzru, who last year refused the John Llewellyn Rhys award as he objected to the politics of its sponsor the Mail On Sunday, tackles both cyberspace and immigration in his new novel. But at the heart is globalisation and the way it allows a virus to bring together three totally unconnected individuals - an Indian immigrant to the US, a marketing boss and a Bollywood actress.
Kunzru told BBC World Service's The Ticket programme that it was unusual for him to have such a definite starting point for his work.
"Usually for me it's a very non-rational set of starting points - they're often images, or just odd conceptual connections," he said.
"With this book there was a definite starting point with the image of a young guy walking along the side of an American road with fast cars driving past, and another image of somebody down on the beach, having been washed up on the shore.
"They felt, for whatever reason, like they were part of the same thing, and the rest of the whole tottery edifice gets built up on those."
'Fake globalism'
Transmission focuses on the contrast between Guy Swift, the cocaine-addled head of a marketing consultancy from England, and Arjun Mehta, who has great difficulties as an immigrant getting into and getting on in America.
Arjun seeks a job in Silicone Valley, but is swiftly fired as the company are able to continually bring in ever-cheaper foreign workers.
In his anger, Arjun releases a computer virus that begins to affect people's lives worldwide.
Transmission is, however, as much about mobility as computers, with Guy able to go anywhere at a moment's notice, and Arjun struggling to find his way as a restricted-stay foreigner in America.
"I think we're living in a world where ease of travel is becoming almost the defining sign of status," Kunzru said.
"If you have the right citizenship and you have money, you can flit across the surface of the Earth. But for other people, their kind of rootedness in place and their inability to move is a sign of their low status, of their oppression under globalisation.
"The real difficulties of the people at the bottom of the tree are only glimpsed at the edges, in the distance - they're serving drinks or they're doing the dirty work to facilitate the lives of the mobile and wealthy."
The book also reveals what Kunzru called his despair at "fake globalism."
At one point, Guy declares his mission is to mine the "emotional magma that wells from the core of planet brand."
Meanwhile the character of Arjun's sister works in a call centre in India, fielding calls from New South Wales. During this time she learns how to speak in an Australian accent - although she does not perceive this as a negative thing.
"She's having quite a good time, and is enjoying learning about Australia," Kunzru stated.
"It's kind of a good thing - much to the wonder of her traditional middle-class parents."
Pro-American
But Arjun does not fare so well.
In contrast to his sister, dealing with the West from within India, Arjun is alone in the heart of the global system.
"He, like many migrant workers, faces the difficulties of not having proper citizenship status in the places where he's trying to live and work," Kunzru stated.
"He believes in America whole-heartedly - he's a really pro-American character.
"But he's on a very restrictive visa, which allows US companies to bring in cheaper talent from abroad. He finds that even in the land of plenty there is relative poverty, and that kind of suburban environment he's trying to move around in as a non-driver is very hostile in a way.
"It's car world - he's almost physically oppressed by the spaces of suburban California."
Overall the book is a satire, mocking excesses of Western life - Guy Swift in particular is the target of much of this, although Gavin Burger, a word-mangling US President, is clearly the subject of some scorn too.
Kunzru stressed he was particularly concerned about marketing, and what he felt "the fact that people are selling us information and people are selling us feelings more and more, rather than just products and services".
"So buying and selling is worming its way into our innermost cells, and that's very dangerous - and potentially, in effect, a profound transformation in our abilities to feel and relate to each other without buying stuff," he added.
