The Gryphon King (The Chaos Constellation #1)

Bataar was only a child when he killed a gryphon, making him a legend across the red steppe.

Now he is the formidable Bataar Rhah, ruling over the continent that once scorned his people. After a string of improbable victories, he turns his sights on the wealthy, powerful kingdom of Dumakra and their vicious pegasus-mounted warriors. Nohra Zultama has no fear of the infamous warlord who marches on her country.

She and her sisters are Harpy Knights, goddess-blessed and lethal. But as deceit and betrayal swirl through her father's court, she soon learns the price of complacency. With Dumakra under Bataar’s rule, Nohra vows to take revenge — yet her growing closeness to the rhah's wife, Qaira, threatens to undo her resolve.

When rioting breaks out and strange beasts incite panic, Nohra must fight alongside Bataar to keep order, her mixed feelings toward the man she’s sworn to kill becoming ever more complicated. Old evils are rising. Only together will Nohra and Bataar stand a chance against the djinn, ghouls, and monsters that threaten to overrun their world.
