Assassin's Heart

Viviana is an assassin, one of the best in all of Avira. She has never failed in executing her missions with precision and timeliness. When she is given a mission seemingly like any other, she stumbles across a secret that could destroy everything she's worked for. As her past catches up to her, can she change the future and save her home or will she the one who destroys it?
