Seventeen knew no other existence but the Institute and its training program. Trained as an assassin since she was a toddler, she must now face the ultimate test—locate the traitors, Two and Four, and exterminate them. For years, Seventeen has longed to escape the Institute, but a one-way ticket to Brevona was not her idea of freedom. To make matters worse, her targets were two of their own—Two, a young woman she considered family, and Four, a trainee from the male division. Sometimes you had to take what you could get, and a life outside the Institute was worth it, no matter the cost.
