Sometimes, you CAN judge a book by this cover. If the cover makes you think “ehh, not my jam,” you probably are not interested in this book. But if you look at the cover and think, as I did, “give it to me now”, you will not be disappointed. It absolutely lives up to the cover. There is tension, buckles are swashed, much pining is pined, and angsting is angsted. Also skulduggery and wool. 
Genuinely, this was exactly what it said on the tin and exactly what I wanted.
