As the Age of Wrath reaches its bloody conclusion, the world will be reforged in steel and fire . . .

Thera Blackspear was once champion to the Sister Queens. Now she's a queen herself, with Elvine as her spear maiden, wielding a weapon forged by the gods. But while the traitorous Sister Lore plots in the shadows, Ascarlia will never be safe.

Felnir has won a crown of his own and forged a kingdom at the tip of his divine blade. Yet his dreams are troubled by visions of the brother he thought long dead. A brother who needs his help, and whom Felnir would give anything to save - even his hard-won kingship.

Ruhlin's many victories have made him a hero to the Morvek, who believe he is the prophesied saviour who will overthrow their Nihlvarian enemies. But now he finds himself a prisoner of the Vortigurn, the King of Nihlvar, who has secrets and schemes of his own. Secrets that could unmake the world.

Upon the Forge of Battle is the epic conclusion to Anthony Ryan's Age of Wrath trilogy.
