Messianic rabbi Jonathan Cahn’s novel, The Harbinger, marks a milestone in 2012 as the longest-running Christian title on the New York Times Paperback Trade Fiction list. The book has also sold 1 million copies.

The FrontLine/Charisma House Book Group title has ranked for 52 weeks on the best-seller list, placing at No. 14 on the Jan. 13 list.

“Competition was stiff this week with the reemergence of books by Nicholas Sparks and the Game of Thrones series, with HBO premiering the new season in a few days,” said Tessie DeVore, executive vice president, Charisma House, the book group of Charisma Media.

The prophetic novel that is a warning to America has ranked on USA Today's Best-Selling Books for 51 weeks and is now at No. 117.

In the Christian market, the book has placed regularly on the Evangelical Christian Publishers Association (ECPA) Christian Best-sellers list, ranking at No. 1 on the January 2013 Fiction list and at No. 6 on the General list. It is also No. 3 on the latest CBA best-seller list.

A new FrontLine title, The Harbinger Companion With Study Guide gives the story behind the story, taking readers deeper into the prophetic revelation in the novel. Featuring a 13-week study guide, photos of the actual harbingers mentioned in the novel, articles, maps and more, the companion work releases Jan. 8.
