The Bloodiest Daughter — Aron Lewes

Daniul has come to terms with an unfortunate fact: he must make contact with the barbarous Black Knight. His mission takes him deep into enemy territory, alone. And it's probably a suicide mission.

Meanwhile, Kelizabeth is captured by the twisted Fellestan king, who forces her to fight in a bloody tournament to the death. There, she'll have to put Eion's lessons to the test.

Please note: This is the third book in The Black Knight Chronicles series. Knowledge of the first two is recommended.
