Khaled Hosseini, the best-selling author of The Kite Runner and A Thousand Splendid Suns, will publish a new novel on May 21, 2013.

And the Mountains Roared (Riverhead) will be Hosseini’s first new book in six years. He said in a statement, “I am forever drawn to family as a recurring central theme of my writing. My earlier novels were, at heart, tales of fatherhood and motherhood. My new novel is a multigenerational-family story as well, this time revolving around brothers and sisters, and the ways in which they love, wound, betray, honor, and sacrifice for each other.”

Over 10 million copies of The Kite Runner and A Thousand Splendid Suns have been sold in the United States, and over 38 million copies of both books have been sold worldwide in over seventy countries.
