Dazzling and erudite … There is something hopeful in this project, in its sheer intellectual ambition and range, its effort to pick apart and decipher the absurdities and ironies of our political derangement, which almost no other writer could pull off. If I had to name a single book that makes sense of these last few dark years, it would be this one.

A deeply compelling read, one which feels urgent and necessary as we enter yet another period of political strife. In Doppelganger, Klein gives shape and context to that apocalyptic mindset – and implores us to offer up an alternative.

A book of surprising insights, unexpected connections and great subtlety … Doppelganger is really a story of political and psychic confusion … True to form, Klein’s ultimate message is log off and get on to the streets.

I’ve been raving about Naomi Klein’s Doppelganger … I can’t think of another text that better captures the berserk period we’re living through.

A deeply insightful inquiry into the ways in which the technology that drives our lives increasingly demands mirror-image doubles, tribal combatants to fuel a divided culture … a powerful antidote. In articulating and examining some of the darker forces of the world her “double” inhabits, Klein never forgets that the primary purpose of mirrors is actually self-reflection; to understand the other, you first have to know yourself.

This book is the product of Klein’s fascination with her doppelgänger. As she charts [Naomi] Wolf’s journey towards extremism, Klein shines a light on the dangers of social media and the new world of online conspiracy theories.

The most comforting book I read this year – Naomi Klein’s Doppelganger tells of her slightly paranoid obsession with Naomi Wolf, her conspiracy theorist “double”. Klein catches that sense that the world has become fictional, but she manages to stay sane, interesting and trenchantly political throughout. In difficult times, this feels very empowering.

Wonderfully esoteric … it expands into the territory of mass confusion: about politics, technology and what we can ever really know.

This story of mistaken identity would on its own be gripping and revealing enough, both as a psychological study and for its explorations of the double in art and history, the disorienting effects of social media, and the queasy feeling of looking into a distorted mirror. But the larger subject of Doppelganger turns out to be a far more complex and consequential confusion … A uniquely astute account of the scrambled political formations that have come out of the pandemic.

Klein wields her polymathic expertise like a sword, slicing through the mirror world … There’s a lot going on in Doppelganger, yet somehow Klein ties it all together into what we seem to be lacking as individuals: a cohesive whole. Doppelganger is both timely and timeless, a work in a grand tradition.
