top-secret-21-196x300John Green is racking up weeks on the bestseller list, getting double credit in the latest edition for his No. 1 bestseller “The Fault in Our Stars” and his No. 20 best-seller “Looking for Alaska”. Both are back-list titles enjoying a resurgence.

With “The Fault in Our Stars”, it’s obvious why the e-book has been No. 1 for weeks. It’s less obvious why Green’s 2006 novel “Looking for Alaska” is seeing a resurgence. USA Today theorizes it’s a halo effect from “The Fault in Our Stars” movie.

Meanwhile, Penguin Random House, Green’s publisher, has 13 of the top-25 spots on this week’s e-book bestseller list. Last week the publisher had 14. PRH also had nearly half the spots on Amazon’s “Best Books of the Year (So Far)” list, which came out earlier this week.

Notable Absence: “The Silkworm”

“The Silkworm”, J.K. Rowling’s latest book under pen name Robert Galbraith, came out last week. It doesn’t appear on the list below because it was not in the top-25 bestsellers across all e-book retailers. It clocked in at No. 30 on our list.

However, if we filter out Amazon Kindle and just look at e-book bestsellers across the other platforms, representing nearly a third of all e-book sales, then “The Silkworm” would have ranked at No. 6.

“The Silkworm” wasn’t available for purchase as an e-book at Amazon until the middle of the morning on the day of its release, Thursday, June 19. Not enabling pre-orders certainly affected the title’s e-book sales.

There’s no way to know what might have occurred had Amazon and Hachette not been in a trade dispute and the retailer did more to push the e-book, but the disparity between sales for a No. 30 bestseller and a No. 6 bestseller should give us some indication that Amazon can powerfully affect the trajectory of bestselling e-books.
