The Familiar by Leigh Bardugo

As a Jewish servant in Madrid during the Inquisition, Luzia leads an intentionally low-profile life. At least until her mistress discovers she uses magic to assist with everyday tasks like heating water and multiplying potatoes. Seeing Luzia as an opportunity to improve her standing among the nobles, her mistress sends her scullion off to a tournament with other miracle workers. With the potential to make something more of her life, Luzia agrees, but finds herself in a political game with only one ally, Santangel, a shadowy figure who vows to protect and mentor her throughout the tournament. Bardugo’s historical fantasy is rich in atmosphere and morally gray characters. Luzia and Santangel are no exception, but find something in each other that they cannot find in anyone else. The Familiar is a slow burn set in the golden age of Spain that blends magic, religion, politics, and romance in an immersive journey of self-discovery and love.
