The Chicago-themed issue of Granta has made a big splash in the city, reportedly selling more copies than Dan Brown‘s “The Lost Symbol” at one local bookstore.

The issue sold so well that Granta had to reprint more issues a week after publication, making it the fastest selling issue of the magazine ever. Here’s a quote from Unabridged Bookstore staffer Ed Devereux: “Copies of Granta 108 are flying off the shelves…we’ve restocked three times already. It’s even outselling Dan Brown!”

As we reported yesterday, Brown’s bestseller has also seen competition from pre-orders of Sarah Palin‘s memoir. Political troublemaker Martin Eisenstadt has mounted a campaign to get Brown’s book back on top (and drum up publicity for Eisenstadt’s book as well).
