The Final Hour — Andrew Klavan

"You're not alone. You're never alone."

Charlie West has held on to that belief, but now he's starting to wonder. He went to bed one night an ordinary high-school kid. When he woke up, he was wanted for murder and hunted by a ruthless band of terrorists. He's been on the run ever since. Now he's stuck in prison, abandoned by his allies, trying desperately to stay a step ahead of vicious prison gangs and brutal guards. And a flash of returning memory tells him another terrorist strike is coming soon. A million people will die unless he does something. But what? He's stuck in a concrete cage with no way out and no one who can help. Charlie has never felt so alone-and yet he knows he can't give in or give up . . . not with the final hour ticking away.
