This was my first time reading Sanderson and it’s clear he is a great storyteller. It felt a little YA to me, which is not a bad thing, but sometimes it seemed like it didn't know if it was going to be an adult or YA story. Nice world-building: the author really takes time to develop the world and bring it to life, without making it boring. The high point of this book was the Magic System based on colors and Breaths. It's intricate and interesting. I like it when magic has rules, restrictions, and costs to the user. There are some good plot twists that caught me totally by surprise.
