'Cunningham's conclusion is decidedly optimistic, if not utopian. . . And it is that abiding, dreamlike cinematic sweep of time - and our place within it - which makes "Specimen Days" an ultimately satisfying, richly rewarding and deeply enjoyable book.' Philip Hoare, Sunday Telegraph
'Thought-provoking.' Independent
'As a novel of ideas, "Specimen Days" manages to be both entertaining and moving. . . puzzling, thought-provoking and well worth having.' Daily Telegraph
