Sightless Savior

He wakes from unconsciousness to find himself seriously wounded and in a dangerous situation. They want information and they’ll do anything to get it. They have the ammunition, the muscle, and the technology no one else does. But he is their biggest problem, because what he possesses could destroy them. He has the knowledge they want, but won’t tell no matter how hard they force him. He can’t. That information may stay locked inside his broken mind forever.
