Mind the Gap: The New Class Divide in Britain | 
pickI found this book very insightful regarding class divisions in the UK today and the continuing reasons for these divisions. Read not long before the tragedy at Grenfell Tower, it puts the antipathy felt towards the working class in sharp focus. As I have only lived in the UK for a few years, social class and issues of social mobility are quite foreign to me, so this was a good read, albeit somewhat disheartening in its conclusions.
