Good news! Early reports show that book sales are up 4.9 percent in 2014. Who can we thank for this Christmas miracle? Adults who read e-book versions of YA novels, that’s who. Sales are up by a dramatic 53 percent in YA/Children’s e-books, while sales in Adult Fiction/Nonfiction are down 3.3 percent—maybe because all the adults are reading The Hunger Games on their Kindles instead.
