Savage in the Heart by Milana Jacks

His heart is set on vengeance. Mine only wants him.
After escaping the vicious horde camping nearby, I need the papers that will get me through heavily guarded gates of Lyan. Desperate for coin to buy those papers, I turn tricks. Until he pins me and offers me a deal: I let him channel my magic, and he walks me inside the city.
It sounds like a great deal.
It really is a great deal.
Except, the man who offered the deal, altho charming, is no honorable prince.
He’s a savage.
A horde male from the people I escaped from.
His heart is set on vengeance.
I’m his means to an end.
I can’t fall for him.
I won’t.
No way.
… And then I do.
