Her Solemn Oath

A skilled assassin. Dangerous terrain. The ultimate sacrifice.

Allison Quinn has one mission—to find the person who killed her father.

As a senior agent for Homeland Security, her job puts her in the perfect position to hunt for answers. But when a cyber terrorist known as Worm threatens to unleash an EMP over Seattle, collapsing the Northwest's communication and transportation systems, her mission becomes even more urgent.

Allison and her partner, Donovan Steele, track Worm to Hurricane Ridge, where they must face treacherous terrain, a brutal blizzard, and a race against time to stop the attack. But Allison isn't just here to prevent a national catastrophe—she's here for revenge. Worm knows the truth about her father's murder, and she will extract it—no matter the cost.

As the storm closes in and the clock runs out, Allison must decide how far she's willing to go. Stopping the attack might require the ultimate sacrifice.
