Description:
Frank McCourt's book Angela's Ashes is a fascinating read and drew me into the social history of the Limerick which existed just before my childhood. As our home is on the side of Limerick depicted in Frank's book I cycled and walked the roads and lanes of his memoirs and found it most interesting to talk to the people who grew up there during that time.
