El desafío final

FBI Agent Atlee Pine has searched for her twin sister her entire life. Mercy was kidnapped at age six while sleeping in their shared bedroom in their family home. Mercy's disappearance left behind a broken family, which was further shattered when Atlee's parents inexplicably abandoned her. After years of investigation, Atlee has uncovered not only the reason for her parents' abandonment and Mercy's kidnapping, but also proof that her twin sister survived the torture and inhumane conditions of her captivity and managed to escape her captors many years ago. However, she has no idea if Mercy is still alive. When the truth is revealed, Atlee will face one final challenge, the most dangerous and one she could ever have imagined.
