J.D. Robb's "Concealed in Death" grabbed the No. 3 spot on this week's ebook bestseller.

J.D. Robb’s “Concealed in Death” grabbed the No. 3 spot on this week’s e-book bestseller list.

For a few weeks it seemed as if Amazon Publishing had finally arrived to compete with the world’s largest publishers, which consistently dominate the Digital Book World E-book Best-Seller list.

For several weeks in a row, Amazon had a handful of top sellers, including a No. 1 e-book best-seller the week ending February 1, a first for the publisher.

After sustaining some of its best-sellers for several weeks, Amazon publishing titles began to slip down the list, and this week there is only one e-book on our best-seller list, which tracks sales across Amazon, Nook, Apple, Kobo and Google. The title is “The Rented Mule” by Bobby Cole, sitting at No. 25 on the list for $4.99.

At the same time, HarperCollins has added another No. 1 best-seller to its pile this year with Veronica Roth’s “Divergent” taking the spot again for the third week in a row. And Penguin Random House again has 10 or more e-book best-sellers, a feat the large publisher has achieved a majority of weeks since it was formed last summer.

Meanwhile, the average price of a best-selling e-book continues to tick up, now sitting at $6.48, up from $6.24 last week.

E-book best-sellers from the week ending 2/22:

1. “Divergent” (Divergent Series), Veronica Roth, HarperCollins, $4.99

2. “The Fault in Our Stars,” John Green, Penguin Random House, $5.50

3. “Concealed in Death,” J.D. Robb, Penguin Random House, $11.99

4. “The Goldfinch,” Donna Tartt, Hachette, $7.50

5. “Allegiant” (Divergent Series), Veronica Roth, HarperCollins, $6.99

6. “Insurgent” (Divergent Series), Veronica Roth, HarperCollins, $6.99

7. “Sycamore Row,” John Grisham, Penguin Random House, $6.49

8. “The Husband’s Secret,” Liane Moriarty, Penguin Random House, $5.99

9. “Private LA,” James Patterson and Mark Sullivan, Hachette, $11.99

10. “The Monuments Men: Allied Heroes, Nazi Thieves, and the Greatest Treasure Hunt in History,” Robert M. Edsel, Hachette, $4.49
