"Karachi Vice'' is a deeply engaging work of narrative non-fiction. The extent of Samira Shackle's research, visits and interviews is clear throughout. These aren't characters in a story. They're real people, with rich lives which Shackle explores with empathy and respect. The book provides some historical detail, particularly with regards to politics. Glossaries and timelines are provided and I found this helpful. Shackle paints a beautifully nuanced portrait of the city of Karachi through the eyes of its residents. I found the book to be an extremely interesting and informative read.
