Dark Lightning — Angela N. Hunt

Sabine Parsons, is no longer an ex-codebreaker. The intelligence fraternity has taken her back and she is once again code-named Oracle and in possession now of a power that makes her an Oracle in truth. Her quiet life is well and truly over. Trying to escape the tightening grip of old/new affiliations, she heads to her father's house, intent on keeping her cover but also planning on making her escape back into the Cold. Except Michael Parsons is a mathematician with ties to the Department of Defense and secrets of his own. Sabine finds herself dropped into an even greater mystery that involves her father and her own past as a ward of Special Projects. All while the Lodge of the Midnight Sun and Edward Quintaine's organization wage their secret war, seeking to find weaknesses in the others armor. And in the end, everyone's secrets will be revealed.
