Top Ten Best-Selling Ebooks -- Week of June 14

The success of the film adaptation of The Fault in Our Stars is helping John Green's YA novel hold onto its place at the top of the latest Digital Book World Ebook Best-Seller List.

But perhaps the bigger news, at least for Penguin Random House, is all the company it has on this week's list. A full 14 of the 25 titles ranked are published by Penguin Random House, including five of the top ten excerpted here (you can check out the complete list at Digital Book World).

The merger of Penguin and Random House last year brought together what were then the two biggest publishers in the world, and now their combined size and scope is making itself felt within the book world.
