Stephen Windwalker, editor of The Kindle Nation, reports on Teleread that “Ebooks accounted for 29% of all first week sales of The Girl Who Kicked the Hornet’s Nest,” the third novel in the bestselling Stieg Larsson trilogy.

According to Michael Cader, posting on his Publishers Marketplace website, out of 425,000 units, 125,000 were e-books. That comes to an extraordinary 29.4%. If percentages like that hold up for future frontlist releases, it will be hard to argue that the paradigmatic e-book tipping point has not yet arrived.
