Sisters Vivenna and Siri are princesses. Vivenna has been trained her entire life for her marriage to the God king Susebron, yet when the time has come for her father to send her away, he chooses Siri instead. Vivenna fears for her little sister’s life and decides to go on a rescue mission. Meanwhile, Lightsong, one of the gods that inhabit this world, tries to uncover the secrets to his pasts; for every god loses all memory of his/her life when they enter godhood.
Brandon Sanderson again shows his ingenuity with magic systems in this novel: colour and Breath (a soul-like substance) can be used to give life to objects. Apart from the cool magic, there also was a ton of character development in this novel, especially for Vivenna. She starts out as, well, a princess: highly educated, composed and with the idea that she knows better, she soon realises that no education in the world could prepare her for the real world and that her arrogance is misplaced (even though I can't completely blame her, I understand that it must have been hard on her to have trained her entire life for a purpose that is then suddenly taken away from her). The only con I could find was that it took me a while to get really immersed into the story, because there are quite some POV's.
