When fitting in experiences with seven of the world's most famous gangs in three hundred pages this was never going to contain in depth analysis of every situation. What it does do well is offer a view of what common links there are between the causes of gangs worldwide and how people find themselves drawn in to desperate situations. Which makes it all the more poignant to see the people who choose to live their lifes like this with other options available to them. There is no glamourising at all and some of the stories are powerful and unsettling. Surprisingly decent accompaniment to the TV series. ( )
