When she was just seventeen, the course of Celaine Stevens' life was permanently altered with the murders of her father, mother, and brother in one of a series of mysterious and violent explosions occurring across the country. Struggling with picking up the pieces, she's haunted by the memory of that day and her promise of retribution against those responsible for her misery. But just as she seems to be getting her life back on track, an encounter with a mysterious stranger promises her the vengeance she desires, ultimately turning the former target into the assassin. However, as she soon learns, all choices come with consequences. And the consequence of her choice threatens to destroy the very fabric of her being.

What if you gave up everything you knew and loved for a lie? Nearly one year ago, Celaine Stevens made the choice to leave her life behind to join The Epicenter, an organization charged with bringing down The Man in Black - a terrorist and the one responsible for the murder of her entire family. Battling conflicting emotions and the pain her decision caused, Celaine tells herself that her sacrifices will all have been worth it when The Man in Black is finally apprehended. But, instead of hunting the elusive entity, Celaine and her partner Ian Grant find themselves preparing for a war looming on the horizon. Angered by President Brooks' ever-tightening restrictions, a rebellion has formed, leading the charge against the President and anyone who stands in their way. Caught in the middle, Celaine and Ian are forced to choose sides, having to decide whether to align themselves with the rebellion, whose motives they question, or obey the orders given to them by an organization they are steadily growing to distrust. A war is sparked by deceit, new alliances are formed, an unexpected love begins to blossom, and true identities are revealed in Vendetta Nation, the second installment of the Enigma Black trilogy.

Ten years ago, her family was murdered. One year ago, she left her life behind for a chance to avenge their deaths. Twenty-four hours ago, her defiancé sealed her fate. With her suspicions mounting and her loyalty to The Epicenter tested, Celaine Stevens makes the decision to fight for a cause she believes in and aligns herself with the rebellion. Joined by Ian Grant, the pair escape from The Epicenter and travel to the Capitol, where they find Marshall Leitner and his followers. While inside the rebellion, Celaine and Ian learn that the rebels are planning a final uprising against President Brooks, one in which they hope will sway the rest of the country’s opinion in their favor. However, loyalties are soon tested. The rebels are finding it hard to trust them, so when a bounty is issued on Celaine and Ian by President Brooks, it may be too good for some of them to resist. As the nation goes to war, Celaine finds herself in the fight of her life. Vendettas will become personal, lives will be lost, and her world will change forever.
