A fast paced look at downtown NYC post 9-11 . I enjoyed this book. A portrait of an actress trying to search for her place in the world after witnessing the fall of the twin towers. Great details for those familiar with the locations and people that make downtown New York its own universe. Some names are changed to protect the innocent, but even if you have never ventured south of Times Square, I believe you will be able to enjoy these characters and their attempts to "make it". A quick read (I finished this in one sitting and I am not a fast reader), fast paced, smart and funny. I am looking forward to reading other books by this author
Output:
POS
