For decades, the brothers of the Sixth Order have fought a savage war against the Lonak clans amid the frozen peaks of their dominion. When word reaches the North of a fresh outbreak of the dreaded Red Hand, Brother Sollis, the finest swordsman in the Order, leads a small band to a long-abandoned castle in search of a potential cure but discovers a far greater threat lurking in the mountains. Enemies become allies as Sollis leads an increasingly desperate fight against an inhuman enemy steeped in the power of the Dark.   

The Omehi people have been fighting an unwinnable war for generations. The lucky ones are born gifted: some have the power to call down dragons, others can be magically transformed into bigger, stronger, faster killing machines. Everyone else is fodder, destined to fight and die in the endless war. Tau Tafari wants more than this, but his plans of escape are destroyed when those closest to him are brutally murdered. With too few gifted left the Omehi are facing genocide, but Tau cares only for revenge.

Gavin Guile is the Prism, the most powerful man in the world. He is high priest and emperor, a man whose power, wit, and charm are all that preserves a tenuous peace. But Prisms never last, and Guile knows exactly how long he has left to live: Five years to achieve five impossible goals. But when Guile discovers he has a son, born in a far kingdom after the war that put him in power, he must decide how much he's willing to pay to protect a secret that could tear his world apart.

At the Convent of Sweet Mercy, young girls are raised to be killers. In a few the old bloods show, gifting talents rarely seen since the tribes beached their ships on Abeth. Sweet Mercy hones its novices' skills to deadly effect: it takes 10 years to educate a Red Sister in the ways of blade and fist. But even the mistresses of sword and shadow don't truly understand what they have purchased when Nona Grey is brought to their halls as a bloodstained child of eight, falsely accused of murder - guilty of worse.

Clay Cooper and his band were once the best of the best - the meanest, dirtiest, most feared and admired crew of mercenaries this side of the Heartwyld. But their glory days are long past; the mercs have grown apart and grown old, fat, drunk - or a combination of the three. Then a former bandmate turns up at Clay's door with a plea for help: his daughter Rose is trapped in a city besieged by an enemy horde 100,000 strong and hungry for blood.
