The rebellious son of a long line of pureblood cartographers and diviners, Valen has spent years trying to escape the life ordained for him. His own mother predicted how he would meet his doom-and her divination is nearly fulfilled when he winds up half-dead, addicted to an enchantment that converts pain to pleasure and possessing only a stolen book of maps. Offered sanctuary in a nearby monastery, Valen discovers that his book-rumored to lead men into the realm of angels-gains him entry into a world of secret societies, doomsayers, monks, princes, and madmen, all seeking the key to the doom of the world. Now, to preserve the lands of Navronne, Valen must face what he fled so long ago. For he alone can unlock the mystery that can save the world
