For generations, the Seven Prophets guided humanity. Using their visions of the future, they ended wars and united nations - until they disappeared, one hundred years ago.

But they left behind 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. As a dark new power begins to make war on the magically gifted, five souls are set on a collision course that will determine the fate of their world.

One of them - or all of them - could break the world. Will they be saviour or destroyer?
