If you were ever looking for a coffee table book that may ensnare a guest's attention if they choose to pick it up and 'glance' through it, City of Darkness is one of the best. Unfortunately, it is now a collector's item now (hundreds of dollars)

Note: There is a 2nd edition coming out soon (via Kickstarter)
