Disgraced FBI agent Ethan Lange is on the run. Accused of colluding with terrorists, he has nowhere to turn, no one to trust, until Sarah Maier needs his help. When Ethan saves Sarah and her two little sons, he binds himself to them, entwining their fate with his. Ethan is no stranger to violence having spent his undercover career infiltrating terrorist cells. When those same terrorists invade the National Gallery in Washington, D.C., Ethan is once more in the line of fire. And when Ethan brings Sarah, Teddy and Charlie into a safe house with him, the terrorists shift their deadly focus to the little family who become enemies by their mere association with Ethan. Rather than protecting them, Ethan exposes them to the dangers of gunmen, bombs and fire. Embarking on a cross-country journey, Sarah and Ethan travel from Washington, D.C. to Colorado evading capture while trying to piece together the means of Ethan's redemption. With the help of New York Times investigator Johnny Parsons, Ethan must protect his charges and solve the mystery of a Chechen mercenary and a U.S. Senator. But the mountains are not quite the escape that Ethan was hoping. Mercenaries, grizzly bears, rattlesnakes and the FBI threaten his life and his hope for a future with Sarah.
