Sold To My Mates Brother

He is my mate. A demon, Satan reincarnated. The cruelest of all cruel Alphas. His name is Lucifer, after all. Until I learned the hard truth; I was nothing more than a weapen forged to hunt my own kind. I'll hunt, just not my people, but the ones that made me. Though I'm gonna need my mate's help, problem is, will he forgive and help me after everything I’ve done?
