Oath of Blood and Shadow

Book excerpt: It's not every-day your uncle tries to kill your entire family and burn your house to the ground, all to keep a life altering secret hidden. Unfortunately for him, he should have hired better mercenaries. My name is Anna Arnoth and I found his dirty little secret. To date, I have survived two assassination attempts. Unfortunately, the third was more successful. In the blink of an eye my world was changed forever, I was twenty-six and I had a knife sticking out of my chest. This is where my story would have ended if it wasn't for the girl clad in black. With my last breath she gave me an offer I couldn't refuse, an offer to seek the revenge I desired. There was just one small catch, I had to swear an oath that even death couldn't break. Only now as I enjoy a life-giving breath, am I willing to ask the question. At what cost was this new lease on life?
