J.R. Ward said in late March that the next book in her Black Dagger Brotherhood series would be titled The King, and would continue Wrath's story—and now there's a cover!
It's also up for pre-order. Here's the scant official information:
The newest installment in J.R. Ward’s #1 New York Times bestselling Black Dagger Brotherhood series. Wrath and the Brotherhood are locked in an epic battle over his throne and the very future of the vampire race.
The King will be released March 25, 2014.
