Top Ten Best-Selling Ebooks -- Week of May 17

This week finds John Green's The Fault in Our Stars hanging onto its No. 1 position on the Digital Book World Ebook Best-Seller List, after Penguin Random House lowered its price from $7.40 to $4.99.

Several other ebooks on the list are cheaper now than they were a week ago, including several Hachette titles. The publisher's standoff with Amazon during suspected contract negotiations could have contributed to higher price-points for some of them last week.

And speaking of Amazon, the company's publishing arm sees further successes with Moving Day by Jonathan Stone holding steady for the second week in a row at No. 2, plus two additional titles in the top ten.

1. The Fault in Our Stars by John Green (Penguin Random House) -- $4.99

2. Moving Day: A Thriller by Jonathan Stone (Amazon) -- $4.99
