Given the importance afforded to the 1930s as a time of economic and political crisis in Western society (the 'dark valley' of the title), it is remarkable that no one has previously attempted such an over-arching narrative history of the decade spanning events in Europe, the Americas and the Far East. Brendon writes with the authority and clarity of the expert, yet his lightness of touch and descriptive talent make this book a delight. The chapters are focused mainly on major political events of the 1930s, but also encompass the realities of everyday life and the experiences of the decade for ordinary people. The inclusion of cultural references not only testify to the erudition of the author, but also provide a well-rounded feel to the book as whole. A great book to dip into; you'll be both informed and entertained. (Kirkus UK)
