Reading High Weirdness is a bit like reading Dante’s Inferno. Davis performs admirably as the book’s Virgil, poking around amid radioactive embers while touring readers through the literary remains of various occult ground zeroes and psychedelic Superfund sites of the 1970s. Like the weird fictions it analyzes, the book activates one’s internal Geiger counter. Readers are warned at the outset to proceed with caution — and rightly so, as what follows provides cause for both awe and dread. I can think of no other book that resonates so readily with the opportunities and perplexities of our moment.
