War by Ker Dukey

I planned to get an in, to the Kings of Sin Clubhouse.
Stay under the radar.
Learn information.
Survive.
I came for vengeance.
Not friendship. Not a family. Not love
Yet here I am, drowning in all of those things.
Callan ‘Pain’ Cox was supposed to be the enemy.
But I’ve become addicted to his touch—taste—punishment.
With my secrets laid bare, those around me continue to hide theirs.
Betrayal comes in many forms, but nothing cuts deeper than when it’s from someone you least expect.
I came for vengeance.
I start a war.
