God-Emperor Kairominas is lord of all he surveys. He has defeated all foes, has united the entire world beneath his rule, and has mastered the arcane arts. He spends his time sparring with his nemesis, who keeps trying to invade Kai’s world.

Except for today. Today, Kai has to go on a date.

Forces have conspired to require him to meet with his equal—a woman from another world who has achieved just as much as he has. What happens when the most important man in the world is forced to have dinner with the most important woman in the world?

After bursting onto the fantasy scene with his acclaimed debut novel, Elantris, and following up with his blockbuster Mistborn trilogy, Brandon Sanderson proves again that he is today's leading master of what Tolkien called 'secondary creation,' the invention of whole worlds, complete with magics and myths all their own.

Warbreaker is the story of two sisters, who happen to be princesses, the God King one of them has to marry, the lesser god who doesn't like his job, and the immortal who's still trying to undo the mistakes he made hundreds of years ago.

Their world is one in which those who die in glory return as gods to live confined to a pantheon in Hallandren's capital city and where a power known as BioChromatic magic is based on an essence known as breath that can only be collected one unit at a time from individual people.

By using breath and drawing upon the color in everyday objects, all manner of miracles and mischief can be accomplished. It will take considerable quantities of each to resolve all the challenges facing Vivenna and Siri, princesses of Idris; Susebron the God King; Lightsong, reluctant god of bravery, and mysterious Vasher, the Warbreaker.
