Eva Lockhart, vampire of the Kairi tribe, never even dreamed of crossing the border, a river that seperates her tribe from the Theon tribe. Not only is it against the law, but it puts her life in danger. Everyone knows that the tribe on the other side of the border are ruthless, not to be in contact with. "Darkness is born and bred there" her father had said. But when her younger sister, Avery, takes the dare to run across the border and back, putting her life in danger, Eva must jump across to save her. In doing so, she is caught by Darien, one of the protectors of the other tribe and taken to the other tribe's prison for a death sentence.
But when a common enemy attacks the Theon tribe, and accidentally sets her free, will she stay and fight, or run and be free? Can the two tribes have their differences be put aside to save eachother?
When Darien offers to further train Eva, will they develop more than just skills?
