The repeated confusion of the author’s name with that of Naomi Wolf became ever more disturbing as ‘Other Naomi’ slid deeper into alt-right conspiracy theories during the pandemic. Klein follows her unwanted doppelganger through the looking glass into a darkly surreal mirror-world of disinformation and extremism to give a startling portrait of contemporary US politics. A shrewd, witty and well-judged examination of the idea of the double, in which shadow-selves and shadow-worlds reveal much about our own selves and our times.
