Prepare for the final descent into darkness. Sunday Times and New York Times bestselling author Peter V. Brett brings one of the most imaginative fantasy sagas of the twenty-first century to an epic close. The war has begun… For time out of mind, bloodthirsty demons have stalked the night, culling the human race to scattered remnants dependent on half-forgotten magics to protect them. Two heroes arose―men as close as brothers, yet divided by bitter betrayal. Arlen Bales became known as the Painted Man, tattooed head-to-toe with powerful magic symbols that enable him to fight demons in hand-to-hand combat―and emerge victorious. Ahmann Jardir, armed with magically warded weapons, called himself the Deliverer, a figure prophesied to unite humanity and lead them to triumph in Sharak Ka―the final war against demonkind. But in their efforts to bring the war to the demons, Arlen and Jardir have set something in motion that may prove the end of everything they hold dear―a Swarm. Now the war is at hand, and humanity cannot hope to win it unless Arlen and Jardir, with the help of Arlen’s wife, Renna, can bend a captured demon prince to their will and force the devious creature to lead them to the Core, where the Mother of Demons breeds an inexhaustible army. Trusting their closest confidantes, Leesha, Inevera, Ragen, and Elissa, to rally the fractious people of the Free Cities and lead them against the Swarm, Arlen, Renna, and Jardir set out on a desperate quest into the darkest depths of evil―from which none of them expects to return alive.
