The Double Bind - Finished

I finished The Double Bind by Chris Bohjalan tonight. I would recommend it. The ending was a twist I didn't think was coming. 

The Double Bind is about a girl with a traumatic incident in her past, who now works at a homeless shelter. One of her elderly clients at the shelter dies and leaves behind a box of photographs, many of which are of famous people. It becomes obvious whoever took these photos was quite talented. The main character, Laurel, goes on a quest to find out the meaning behind the photos and who the man was who took them.
