It feels like every Bardugo novel I pick up is better than the last. She is absolutely an author who works to improve her craft with every novel, which is very nice to see.  

The Familiar is set in Spain, during the Inquisition, and follows Luzia, a young woman who is employed as a scullion, who is able to perform fests of magic called milagros, or miracles.  When her gift is discovered, she attracts the attention of some powerful men, and enters a tournament to attract the notice of King Philip, with the goal of putting aside her servants life and reaching for better things. 

It was an excellent novel, very well written, with a satisfying romance and enough intrigue to keep me hooked.
