The late 1970s were Britain's years of strife and the good life. They saw inflation, riots, the peak of trade union power - and also the birth of home computers, the rise of the ready meal and the triumph of a Grantham grocer's daughter who would change everything. Dominic Sandbrook recreates this extraordinary period in all its chaos and contradiction, revealing it as a turning point in our recent history, where, in everything from families and schools to punk and Doctor Who, the future of the nation was being decided.
