TL:DR; Essential for any Sanderson/YA fan. A brilliant book that is submitted as a 'Young Adult' novel but easily surpasses every entry I can think of (Hunger Games/Divergant/Rangers Apprentice etc) for that genre. If you haven't read Sanderson before, this is one of his best. Disclaimer: I'm an avid Sanderson reader and this is, imo, one of his best pieces. I first read Warbreaker while waiting for the next Robin Hobb and was pleasantly surprised with it - and he's only gotten better. I want to say its 'shorter' than his other books, such as the epic fantasy Words of Radiance, but I think 'concise' is a more accurate term. His characterisation, worldbuilding and exposition is among the best of any sci fi/fantasy and EASILY the best I've ever read in a 'Young Adult' novel. He handles twists like a street magician; one hand gestures while the other takes your change. Several times I finished a chapter and had to take a moment, or I punched the air with glee. 9/10, a near perfect sci-fi adventure that is easily one of the best YA books of all time, and a strong entry for most 'grown-ups' as well.
