Some mistakes you never stop paying for. For former assassin Brent Savage, that price has just become his life.Six months ago, he brought down the Darkwater Program, exposing a corrupt president and a conspiracy of state-sanctioned murder. It was a victory forged in blood and fire-one that should have earned him his freedom. Instead, it left him longing for a life he can't have and chained to a past he can't escape.Now, a new president has taken power, unleashing a deadly breed of cybernetic assassin-hunters to take out every last Darkwater operative. They're faster, stronger, and more lethal than Savage ever was-and if they discover he's still alive, they'll stop at nothing to eliminate him...this time for good.But Savage isn't hiding. Deep in the scrub desert of West Texas, he's on a personal mission to track down former president Turner-the man who ordered the assassinations of innocent civilians-and deliver his own brand of justice. The operation goes sideways when Savage is poisoned by a lethal dose of neurotoxin. Now, his genetic modifications and nanobots are the only things keeping him alive...but even they are beginning to fail. With time running out and the assassin-hunters closing in, Savage realizes the most terrifying truth of all: they won't just come for him. They'll come for the woman he left behind.And if there's one mistake he won't allow himself to repeat, it's losing her again.
