This book portrays fantasy action and adventure type story. In the universe created by Brandon Sanderson some people can use special powers like flying through the air, increasing their senses, becoming physically stronger etc. by ‘burning’ metals. The ‘burning’ of the metals happens when someone ingests it and ‘burns’ it inside their stomach. How this burning happens is not explained. It is just something that the characters know how to do in their bodies. Once the metal starts burning it grants them special powers. These powers depend on the metal burned.
I must say, this is some never before seen type of mechanism for manifesting super powers. Now, of course there are some rare metals, some forbidden metals, metals whose effects are not known etc etc.
The story is really interesting. I won’t give any spoilers but I will tell this much that it revolves around conflict between powerful and weak people. The powerful people are royalties as well as people who are exceptionally well versed in ‘burning’ metals. The weak are the slaves and the workers. You get the idea.
This is a really nice read and it also contains some romance. I hope it will help you in deciding whether you want to buy this book or not. Thank you. ^_^
