PositiveLiterary Review (UK)Garrett is a bright and buoyant guide and Bunker rattles briskly along. And he’s scrupulously fair to his subjects, mostly letting them speak for themselves. Indeed, a weakness of the book is that it is too fair to them. Fundamentally, prepping is a bleak and unpleasant philosophy. It might seem like a form of responsible cautiousness, but really it’s a bet against the rest of us ... Some of them appear to be egging the apocalypse on, eager for their underground investments to pay off. Given that, it’s deeply troubling to learn that many of the world’s richest people have a sideline in prepping, getting their off-grid doomsteads in New Zealand ready. But that’s what makes Bunker a necessary read—we should be keeping tabs on what they’re up to.
