BOYD: Lethal Vitals (US Marshals: Task Force 9 #1)

Dr. Iris Kincaid witnesses a murder she was never supposed to see.

One moment, she’s working a routine shift in the emergency department.

Next, a patient is executed in front of her by an assassin tied to the Consortium—a global criminal syndicate that owns judges, politicians, and the justice system itself.

Now Iris is a marked witness with a death sentence.

Her only chance of survival is Deputy U.S. Marshal Boyd Vance. Known as the Hammer, Boyd is the most feared operative on Task Force 9, an off-the-books U.S.

Marshals unit deployed when standard law enforcement is no longer enough. Hard. Calculating. Built for violence. Boyd doesn’t protect witnesses—he neutralizes threats.

His extraction plan is simple: disappear Iris. Off-grid. Deep in the mountains. Inside the Glass House, a fortified safehouse designed to survive siege warfare. Then a blizzard traps them together.

Snowed in with a lethal protector whose control is as dangerous as the killers hunting them, Iris discovers the man beneath the weapon. Every shared breath strips away another boundary.

Every touch ignites a fire neither of them can afford.

But the Consortium finds them. Now Boyd and Iris are trapped in a fortified mountain safehouse, outgunned, isolated, and running out of time. Boyd was assigned to protect a witness.

He’ll become the most dangerous thing in the storm to keep her alive.
