A deadly outbreak. A government conspiracy. Luke's back in the game. Luke Preston's world shattered following the brutal loss of his wife in a police-led operation. Scarred by this personal tragedy, he shelved his detective badge permanently. Former soldier and ex-cop, Luke has since settled into the quiet rhythms of civilian life. But the emergence of a lethal contagion menacing American lives wrenches him from this tranquil existence. When tragedy strikes a family at a secluded detention facility, bearing the hallmark symptoms of a baffling disease, the government rings Luke's number. This insidious illness, marked by harrowing fatalities and eerie blood splotches beneath victims' skin, is on the rise. With time as the enemy, Luke has to plunge into action, or the nation faces a full-blown epidemic. Joining forces with the brilliant medical professor, Mia Mendez, Luke ventures to the borderlands. Their discoveries there are indications that this dread disease isn't natural, but a weapon, masterminded with sinister intent against the very core of the state. Pitted against formidable adversaries, it's up to Luke, with his resourcefulness and grit, to neutralize the shadowy group orchestrating this crisis. Retreat is off the table. From the desk of a USA Today bestselling author comes an adrenaline-fueled thriller. Enthusiasts of Robert Dugoni, Lee Child, James Patterson, and James Rollins are in for a rollercoaster ride.
