From USA and New York Times bestselling author K.M. Moronova comes the conclusion to her delicious, arranged-marriage romantasy, CRUEL FATES DUET. Love is the sharpest weapon of all. Born with gilded blood, Alira is a demigod knight forged for war - her rare gift makes her both priceless and disposable in the eyes of the gods she serves. When centuries of bloodshed threaten to consume the world, she is sent into a political marriage with Kalel Lornhelm, the infamous Blood Knight and demon commander of Devicit. Devicit is a kingdom of beauty and terror, hidden behind a shimmering magical veil. As Alira is drawn into demon life, mistrust slowly gives way to desire, and Alira learns that Kalel has been bound to her fate far longer than she ever knew.

But beneath the city's splendour lies a devastating secret. As gods rise, war reignites, and the systems that shaped them both demand blood once more, Alira and Kalel must confront the cost of peace.
