Three Americans recount their experience of being held captive in Iran’s Evin Prison after unknowingly crossing the Iraq-Iran border while out on a hike. An excerpt from A Sliver of Light, a co-written book about their ordeal:

SHANE (October 2009)

Solitary confinement is the slow erasure of who you thought you were. You think you are still you, but you have no real way of knowing. How can you know if you have no one to reflect you back to yourself? Would I know if I was going crazy? The longer I am alone, the more my mind slows. All I want to do is to forget about everything.

But I can’t do it. I am unable to keep my mind from being sharply focused on one task: forcing myself not to look at the wall behind me. I know that eventually, a tiny sliver of sunlight will spill in through the grated window and place a quarter-size dot on the wall. It’s ridiculous that I’m thinking about it this early. I’ve been awake only 10 minutes and I should know it will be hours before it appears.

They take everything from us—breezes, eye contact, human touch, the feeling of warm wet hands from washing a sink-load of dishes, the miracle of transforming thoughts into words on paper. They leave only the pause—those moments of waiting at bus stops, of cigarette breaks. They make time the object of our hatred.

I try not to look for the light.
