The Assassins Guild

Nine wasn't born to be an assassin. Too small they said. Too weak. Too disappointing. Against all odds she survives her Russian family, an aristocratic lineage of assassins that goes as back as Rasputin itself. As a second level assassin things start looking promising for her.
Until she makes one little mistake.
One mistake that attracts the Kings of Assassin's attention. Once her best friend, now her enemy, the King will stop at nothing until making her bend the knee.
With the Assassins Guild hunting her down and only small chances of surviving the Assassin's version of the Olympics, Nine would have to face old nightmares and turn into the very beast she always fought not to be.
