Warbreaker
Brandon Sanderson
 Warbreaker tells the story of two princesses, Vivenna and Siri. Vivenna was contracted through treaty to marry the God-King of rival nation Hallendren. Instead Siri is sent to meet the treaty. Vivenna then follows to Hallendren in hopes of saving Siri from her fate. Both sisters become involved in intrigues relating to an imminent war between their home nation of Idris and Hallendren. The book uses a system of magic, "BioChromatic Breath", which allows mages to bring life to objects as well as provide benefits directly to the mages, such as perfect pitch, perfect color recognition, perfect life recognition, and agelessness. Use of BioChromancy drains the colors from surrounding objects and the less colorful an object is, the more difficult it is to apply BioChromancy to it. The system has been praised as a unique and original magical system.
