Kingdom of Venom by Quinn Loftis

What’s a girl got to do to get an antidote?

The Viper King Azure, ousted from his throne and driven into hiding, is far from forgotten. Lurking in the shadows, he’s meticulously planning his return, intent on unleashing a sinister plot to grow his powers by creating counterfeit animi. The relentless forces of the Kingdoms of Claws and Fangs are on a desperate hunt to find him before he can wreak further havoc.

And Azure is not without powerful allies. A mysterious voodoo priestess with her own hidden agenda aids him, making the pursuit even more treacherous. For one determined warrior, Katy Dire, this mission is personal. Under the priestess’s dark spell, Katy’s life is bound to the souls of two captive women—if they die, Katy is freed, but if Katy perishes, they survive.

Her mate, Gage, knows what Katy would sacrifice to save others. Frantic and resolute, Gage races against time to locate Azure and the priestess, determined to break the curse and save his beloved from a perilous limbo. The stakes are high, and the clock is ticking in this epic battle of courage and love.
