Callahan (en Inglés) - K.M. Cole

Something was taken from him.

He never really learned how to let things go. He doesn't hesitate. He doesn't forgive.

And he doesn't walk away from anything unfinished.

What starts as a promise turns into something else.

Something quieter. More controlled. Harder to stop once it's begun.

But revenge has a way of stripping everything down.

And somewhere between the hunt and whatever comes after, one truth keeps pressing in: The person who never left...might be the one he was never supposed to lose.
