Dan Brown's publishers have released the prologue and first chapter of his latest novel in the Robert Langdon series, Inferno, which I've embedded above for your reading pleasure. The book begins with the usual (sometimes controversial) Brownian statement that "all artwork, literature, science and historical references in this novel are real", and mentions a pseudonymous organisation known as 'The Consortium' which will apparently feature in the novel (saying the name has been changed for "considerations of security and privacy".
The book opens by referencing Dante's Inferno and a few of the famous locations in the Italian city of Florence. If you've checked out my primer to the new novel, Inside Dan Brown's Inferno, you should be well aware of the significance and details of each of these - if you don't have it, you can grab the eBook for just $2.99.
Update: Also, to celebrate its 10th anniversary Dan Brown has made The Da Vinci Code eBook available for free all week. Go grab it while it's available!
