A race against time. A high-tech threat. And no one can be trusted.

Allison Quinn won't stop until she finds her father's killer.

When a high-tech cyberattack cripples a luxury cruise liner, Department of Homeland Security agent Allison Quinn is sent to the Gulf Coast of Texas. Partnering with Donovan Steele—a man who is sometimes her ally, sometimes her adversary—she must uncover who's behind the attack before chaos spreads. But for Allison, this mission isn't just about national security. It's personal. There's a connection between the terrorists and the person who killed her father. Taking them down might be her only chance at justice.

As the evidence points to a group called Anarchists for Tomorrow, Allison realizes the attack is just the beginning. What could terrorists hope to accomplish by disabling one ship? The horrifying answer sends her racing from Galveston to Costa Luna to Cozumel, navigating exotic locations, shifting alliances, and a web of deception to stop a plot that threatens to cripple the U.S. economy.

But the deeper she digs, the clearer it becomes that stopping these criminals may demand the ultimate sacrifice.

Against All Enemies is a high-octane thriller about one woman's relentless pursuit of justice in a world where trust is a luxury—and betrayal is deadly.
