From the Wall Street Journal: They’re no bodice rippers, but Amish romances are hot.

Beverly Lewis, who sets her novels among the Amish in Pennsylvania, has sold 13.5 million copies of her books. Wanda Brunstetter’s novels take place in Amish communities in Ohio, Indiana, Missouri and Pennsylvania, and have sold more than four million copies. Publishing house Thomas Nelson plans to release five Amish novels this fall, and six more in 2010.

Barnes & Noble book buyer Jane Love said Amish novels currently account for 15 of the chain’s top 100 religious fiction titles. “It’s almost like you put a person with a bonnet or an Amish field in the background and it automatically starts to sell well,” Ms. Love said.
