Bloody Seven by K.M. Baker

Seven years.
Seven murders.
Seven deadly sins.

I made a vow one Valentine’s Day, when they killed him in front of me.
On a day that is supposed to be full of love, now I return with vengeance.
They call me The Cupid Killer and nobody in this city is safe from my wrath.
Truths unveiled. An unexpected ally. And a new promise.
Will anyone make it out alive, or will lust lead to their demise?
