Recently, the Amazon bestseller list and Kindle bestseller list have looked quite different in the top 10, with the former skewing toward more serious nonfiction hardbacks and the latter skewing toward low-priced fiction titles. On the morning of February 9, however, two titles were in the top 10 on both lists: Kill Shot by Vince Flynn (#5 hardcover; #4 Kindle) and Once Upon a Secret: My Affair with President John F. Kennedy and Its Aftermath by Mimi Alford (#8 on both lists). Perhaps compounding the significance of the list overlap is that one title is fiction and the other is non-fiction, showing a synergy for how people read across more than one genre.
