How can she protect herself from an enemy she can’t see?

Law school graduate Whitney Garrison is a survivor. She admirably deals with an abusive boyfriend, her mother’s death, mounting student debt, dwindling job opportunities, and a rare neurological condition that prevents her from recognizing human faces.

But witnessing a murder might be the crisis she can’t overcome.

The killer has every advantage. Though Whitney saw him, she has no idea what he looks like. He knows where she lives and works. He anticipates her every move. Worst of all, he’s hiding in plain sight and believes she has information he needs. Information worth killing for. Again.

As the hunter drives his prey into a net of terror and international intrigue, Whitney’s only ally, Detective Leo Baroni, is taken off the case. Stripped of all semblance of safety, Whitney must suspect everyone and trust no one—and hope to come out alive.

Georgie Brennan may be a world-class quantum physicist, but she grapples with life as a single mother after her husband is killed. When she receives a message from beyond the grave, it leads her to question the details of her husband's death.

As she follows the clues he left behind, her discoveries increasingly implicate those closest to her. When her father is nominated as the new United States Secretary of Defense, she must uncover the truth before his confirmation hearing-even as the same people who killed her husband are now after her.

Nothing is as it seems. Lies are truth; enemies are friends. Even her child is at risk.

As every possibility but one disappears, Georgie may find herself to be the antithesis of everything she's thought herself to be.
