From Brandon Sanderson's website:

"And so, we are introduced to four characters in this book. Lightsong is a God of the Hallandren people—a regular man who died in a heroic way, and was therefore brought back to life by the magic to rule as a god. (Or, at least, that's how the Hallandren people interpret it.) We have Siri, a rebellious daughter sent by her father to marry the tyrant god-king of those same Hallandren people. We have Vivenna, sister to Siri, who goes to try to rescue her sibling from her fate. And then, there's Vasher—whose motivations and goals are his own. (You can read about him in the prologue.)

The magic is one I've wanted to put into a book for a long, long time and the setting—with its vibrant color and tropical climate—is very different from the worlds of MISTBORN or ELANTRIS. This is the book I wrote when I, myself, got engaged and married, and I think it had a great influence on how I interpret the world."

That's the most general, generalized concept of the book, but there's more to it than that.
