There will come a darkness : an age of darkness novel
(Book)

For generations, the Seven Prophets guided humanity. Using their visions of the future, they ended wars and united nations-until the day, one hundred years ago, when the Prophets disappeared. All they left behind was one final, secret prophecy, foretelling an Age of Darkness and the birth of a new Prophet who could be the world's salvation . . . or the cause of its destruction. With chaos on the horizon, five souls are set on a collision course: A prince exiled from his kingdom, a ruthless killer known as the Pale Hand, a once-faithful leader torn between his duty and his heart, a reckless gambler with the power to find anything or anyone., and a dying girl on the verge of giving up. One of them-or all of them-could break the world. Will they be savior or destroyer? -- from Amazon.
