Marked by the author's wide experience writing on British leaders such as Balfour and Gladstone and his tenure as a member of Parliament, his book adds much to the vast library of works on Churchill. While acknowledging his subject's prickly nature, Jenkins credits Churchill for, among other things, recognizing far earlier than his peers the dangers of Hitler's regime. He praises Churchill for his leadership during the war years, especially at the outset, when England stood alone and in imminent danger of defeat. He also examines Churchill's struggle to forge political consensus to meet that desperate crisis, and he sheds new light on Churchill's postwar decline. --Gregory McNamee
