Warbreaker  - Brandon Sanderson Interesting idea using colour and breath as a basis for magic, just felt a little too much like concept over story.

In a world where some people return as better forms of themselves to be able to grant one healing, many use this second chance, where they are treated as gods to indulge themselves, until one day, almost like a compulsion they use this power. Above them is the God King, who is to marry, Vivienna from another kingdom is promised to him , she has been groomed for this from birth. Her father sends the unprepared Siri, this will change the world.

Somewhat predictable, entertaining though.
