I like prepper fiction, and because I have lived through a few crises, I am keenly aware how quickly you can unexpectedly find yourself on your own. Unlike the last post-apocalyptic book I read (Traveler series), the author here tries to stay more grounded and realistic. He overdoes the “danger behind every rock” theme (especially nearing the conclusion of book 3) but overall I really enjoyed the story.
The doomsday scenario is plausible but unlikely as depicted in the book. Our risk of grid failure is far more likely to occur via an EMP or solar flare. The fiction here also presupposes a complete absence of ally countries coming to our assistance.
The narrator has the perfect voice for this type of fiction, but his repertoire of available voices is fairly limited.
