Where does a federal witness turn when even one of the most powerful clandestine agencies can't protect you from harm? That is precisely the horrific dilemma facing Mia Trentino. Scheduled as a
witness for the prosecution, Mia returns to Russia to testify against a man whose affiliation with the Russian Mafia led to her terrifying abduction less than a year before. During her
testimony, Mia's safety is entrusted with the members of the Acronym, a covert agency consisting of former FBI, CIA, and international law enforcement agents. Their primary tasks are the war
against international crime and espionage and assisting federal agencies with securing their high-profile witnesses in a special protection program. When Mia arrives in St. Petersburg to take
the stand, her fianc矇 and Acronym agent, Douglas Farland, disappears without a trace and is accused of treason. With only limited protection, Mia suddenly finds herself trying to negotiate a
deadly double-task; can she elude the merciless pursuit of the Russian Mafia in time to find out the truth about Douglas, or will they succeed in silencing her by any ruthless means they can
find... ?
