Warbreaker is, thus far, my favorite book written by Brandon Sanderson.
Although I feel that his writing style is consistently engaging, this book resonated even more with me than usual.
The book is told through the viewpoints of 4 different characters that interact throughout. I feel that his ability to tell a powerful story from the viewpoints of several different people is one of his greatest strengths.
Here we follow two princesses (sisters) a demi-god named Lightsong and a mysterious character named Vasher. One of the things that I love about this book is that even though we're introduced to a whole new world and magic system I feel like he doesn't waste any time with world creation. What I mean by that is that from the get-go it (the book) grabs at you and you never feel (at least I never did) that the story has stalled as more details about his new world are explained. Rather, you learn as you go.
It's full of twists and surprises, the characters you think you'll love/hate often aren't those that you would expect. I hate spoilers in reviews, so I don't feel that I can say anymore
Even though it is connected to most of the other books he's written (e.g., it's part of the Cosmere Universe) as a stand-alone book it is a quick read that can be picked up without any prior knowledge of any characters from the Mistborn books or Stormlight Archives. If you're interested in reading a Brandon Sanderson book without making a big reading/time commitment, this is probably the one that you should start with.
I love this book and highly recommend it to others. However, books are tricky, and I recognize that not everyone is going to like the same books and things that I do. So, of course I can't guarantee that others will love it, but I can promise that if you read it you will at least see how a master storyteller weaves his tale together.
