The Justine Byrne Series

The Traitor Beside Her

Now available!

Justine Byrne can’t trust the people working beside her. Arlington Hall, a former women’s college in Virginia has been taken over by the United States Army where hundreds of men and women work to decode countless pieces of communication coming from the Axis powers.

Justine works among them, handling the most sensitive secrets of World War II―but she isn’t there to decipher German codes―she’s there to find a traitor.

Justine keeps her guard up and her ears open, confiding only in her best friend, Georgette, a fluent speaker of Choctaw who is training to work as a code talker. Justine tries to befriend each suspect, believing that the key to finding the spy lies not in cryptography but in understanding how code breakers tick. When young women begin to go missing at Arlington Hall, her deadline for unraveling the web of secrets becomes urgent and one thing remains clear: a single secret in enemy hands could end thousands of lives.

“An exciting read with historical tidbits, a hint of danger, and a touch of romance.”

The Physicists’ Daughter

The Nazis are no match for the physicists’ daughter

New Orleans, 1944

Sabotage. That’s the word on factory worker Justine Byrne’s mind as she is repeatedly called to weld machine parts that keep failing with no clear cause. Could someone inside the secretive Carbon Division be deliberately undermining the factory’s war efforts? Raised by her late parents to think logically, she also can’t help wondering just what the oddly shaped carbon gadgets she assembles day after day have to do with the boats the factory builds…

When a crane inexplicably crashes to the factory floor, leaving a woman dead, Justine can no longer ignore her nagging fear that German spies are at work within the building, trying to put the factory and its workers out of commission. Unable to trust anyone―not the charming men vying for her attention, not her unpleasant boss, and not even the women who work beside her―Justine draws on the legacy of her unconventional upbringing to keep her division running and protect her coworkers, her country, and herself from a war that is suddenly very close to home.
