''Outskirts'' is an interesting take on a phenomenon of the modern age: the introduction of the green belt of countryside surrounding inner city housing estates. John Grindrod grew up on the edge of one such estate in the 1960's and '70's, as he puts it, ''I grew up on the last road in London.'' Grindrod explores the introduction of the green belt, and the various fights and developments it has gone through over the subsequent decades, as environmental and political arguments have affected planning decisions. Within this topic, he has somehow managed to wind around his personal memories of childhood, producing a memoir with a lot of heart.
