Oathbound

In the third installment of The Legendborn Cycle, Bree Matthews has stepped away from the Legendborn Order and severed her ties to friends and ancestry in an effort to protect herself and those she loves from the cost of her powers. Her choices lead her into a binding bargain with the Shadow King, a shapeshifter who moves between the human world, the demon underworld, and the secret society, in exchange for training her rare abilities. As war looms over a fractured Round Table missing key members, mysterious kidnappings and the deaths of Merlins signal that Bree's past cannot be outrun.
