She was a legendary assassin. Now, she's a blind servant, bound to the noble whose hidden power is the key to her revenge. In one life, I was Viper—the most feared assassin in the kingdom. In this one, I am Lanza—a blind, powerless servant girl. My soul was torn from my body and trapped here by the same Mage-Regent who murdered my target and plunged the realm into a magical tyranny. My only path to vengeance is through the young master I'm forced to serve. Kingsley Wycliffe is handsome, desperate, and magically blocked, a shame that hangs over his noble house. He sees me as a helpless burden. He has no idea that the frail girl guiding him to his chamber is the only person who can unlock the devastating power sleeping within him. Our secret pact is simple: I will be his hidden master, teaching him the deadly arts I mastered in my past life. In return, he will be my hands and my eyes, helping me uncover the conspiracy that shattered both our lives. But as we train in the shadows, a dangerous bond forms between us. His touch ignites a fire I thought had died with my old body. Yet, if he discovers the brutal truth—that the soul of a killer lives behind my sightless eyes—the trust we've built will shatter.
