Last year Edinburgh residents tackled Arthur Conan Doyle's dinosaur adventure The Lost World, last month Dubliners were taking a collective look at The Picture of Dorian Gray, and Brighton's readers are currently engrossed in Ian Fleming's James Bond novel From Russia with Love. Now a new project is hoping to take the "one book, one city" initiative a step further, and get the whole world reading the same novel.

The brainchild of Jeff Howe, author of Crowdsourcing and a contributing editor at Wired magazine, the One Book, One Twitter scheme launches tomorrow. Readers have been voting for the book which they'll be tackling for the past month, with Neil Gaiman's fantasy novel American Gods eventually triumphing over titles including Fahrenheit 451 by Ray Bradbury, Slaughterhouse-Five by Kurt Vonnegut, Song of Solomon by Toni Morrison and The God of Small Things by Arundhati Roy.

"The aim with One Book, One Twitter is – like the one city, one book programme which inspired it – to get a zillion people all reading and talking about a single book. It is not, for instance, an attempt to gather a more selective crew of book lovers to read a series of books and meet at established times to discuss," explained Howe at Wired.com. "Usually such 'Big Read' programs are organised around geography. Seattle started the trend for collective reading in 1998 when zillions of Seattlites all read Russell Banks's book, Sweet Hereafter. Chicago followed suit with To Kill a Mockingbird a few years later. This Big Read is organised around Twitter, and says to hell with physical limitations."

Gaiman, whose novel follows the story of ex-convict Shadow, released from prison and embarking on a bizarre journey across America with the mysterious Mr Wednesday, who claims to be a former god, said he thought One Book, One Twitter was "a great idea – a sort of worldwide book club".

He was, however, slightly concerned about the choice of American Gods, describing himself as "half-pleased and half-not", because it's "such a divisive book". "Some people love it, some sort of like it, and some people hate it ... It's not a book I'd hand out to everyone, because the people who don't know anything about what I've written and who hate it – who might have loved Stardust, or Neverwhere, or The Graveyard Book or Sandman – probably won't go and look any further," the author explained on his blog.

"But it's happened, I'm kind of thrilled that I get to help kick off something this new, and I'm going to do all I can to help. Which, today, will consist of making sure I let all the publishers around the world who have American Gods in print know about this, and, over the next few months, sending helpful or apologetic tweets to people who are stuck, offended, or very, very confused."

On Twitter at @1B1T2010 – with more than 1,500 followers days after launching – and hashtag #1b1t, the One Book, One Twitter project begins officially tomorrow.
