Natalia Nicolaeva is off to study in St. Petersburg, Russia, but when another student is murdered, her life goes spiraling out of control once more. She could choose to just stay out of it, but then, that's not really Natalia's nature. Instead, she opts for the opposite tactic; doing whatever she can to make the killers pay for their crimes.

Vendetta Girl follows Natalia through a labyrinth of Russian computer hackers, corrupt government officials and professional hitmen as she struggles to put together the pieces of a deadly conspiracy. Nobody is quite who they seem in this fast-paced thriller and the only person Natalia can fully trust is herself.
