It’s not who you may think — or, at least, not who I guessed it would be (J.K. Rowling and/or Stephenie Meyer). Instead, according to the U.K.’s bookseller.com, in a poll of Top 10 fiction bestseller charts across nine different countries , the two names that appeared most often are Khaled Hosseini (The Kite Runner and A Thousand Splendid Suns) and Ken Follett (World without End).
Hosseini and Follett made bestseller lists in seven of the nine countries.
So maybe, adult fiction can compete with YA after all. (At least, outside the U.S.)
