Liar by Michele Mannon

Hayden’s everything I fear. A ruthless cartel boss. A killer. A stranger to this town. Yet, I went to him for help anyway.
They say wisdom comes with age. When you’re young, you do foolish things. Seeking him out—foolish. Allowing my headstrong brother to swear loyalty to him—foolish. Falling in love with him—reckless and foolish.
Yet I can’t help wanting him.
Now I’m under his protection, at the mercy of his whims, subjected to his control. Dragged into a violent, dangerous underworld I’ve spent years avoiding.
There’s a hefty price attached to loving a liar like him. Only I didn’t realize it until it was too late.
