Ana Romero is a 100-year-old vampire daywalker who works for the CIA. She has been tasked by the director with finding a mole who has been leaking classified information to enemies of the United States. She must keep her mission a secret from everyone in her division, the Department of Clandestine Affairs, because the number one suspect is her boss, Director Michael Truesdale. Ana is going to have to use every bit of subterfuge she's learned, and even external resources, to solve this case. Ana has a secondary suspect who she thinks is responsible for the leaks, but her boss still looks equally guilty. And there is still the possibility that it's someone else altogether from her division. Can Ana clear her boss's name and learn the identity of the true mole within her division, and can she find the proof to convince the director of the CIA that her conclusions are correct?
