The Bladebone

A powerful band of women warriors must face off against an oppressive enemy in one final showdown that will determine their survival and the fate of their world in this concluding volume in Ausma Zehanat Khan's powerful fantasy series—an epic of magic, bravery, adventure, and the fight for freedom that lies "somewhere between N. K. Jemisin and George R. R. Martin" (Saladin Ahmed).

Armed with the powerful sorcery of the Bloodprint and supported by the
Talisman, the oppressive One-Eyed Preacher is on the verge of conquering
Ashfall, the Black Khan’s capital in the west. Yet not all is lost for Arian,
Sinnia and the Council of Hira. If these brave female warriors can uncover the
secrets of an ancient magic weapon known as the Bladebone, they can defeat the
Preacher and crush his cruel regime.
Neither
Arian and Sinnia, nor their allies, the Mages of Khorasan, know the Bladebone’s
whereabouts, and not all may survive the search to uncover it. Pursued by a
nefarious enemy aligned with the Preacher, they become separated, each
following a different path. Then, in their darkest hour, unexpected help
appears. But is the Khanum of Black Aura a friend or foe? Arian may discover
the answer too late.
When
the secret of the Bladebone is finally revealed, the knowledge comes at a
devastating price for Arian. As the capital falls, only Hira, home of the
Companions, stands in the way of the Preacher’s victory. While the Companions
rise to defend their Citadel from enemies outside and within, Arian must face
off in a cataclysmic battle with the Preacher that pits the powers of the
Bloodprint against the Sana Codex. 
For those who survive, Khorasan will never be the same.
