'Sophia was once the Fifth Column’s most dangerous weapon.

'Now she’s their greatest threat.

'Intercepting Fifth Column operatives before they can complete their deadly missions, Sophia is deprogramming them and turning them against their masters. But a powerful, new type of operative tips the balance against her, and she barely escapes with her life.

'The rules of engagement have changed, and Sophia is forced onto a collision course with the one person who will save her or kill her—Olesya.

'They’ve crossed paths once before. This time, only one will walk away.'
