Great book to help those interested in the Troubles and/or Belfast better understand the impact that years of paramilitary conflict had on the city. I would recommend watching a documentary as a companion to this book - like Voices from the Grave (which, by the way, is available on YouTube for free) to help you explore more of the specifics.
I found the writing to be more academic throughout, but not to the point that it tired me or discouraged me from reading. It made me appreciate the role of space, walls, and barriers on the segregation that still exists in the city, and furthermore to better understand the role that this segregation plays in both nationalists' and unionists' daily lives (limits both groups' ability and willingness to go grocery shopping, use rec centers, get to and hold jobs, access health care, and find adequate housing).
