When JP finds out his cancer has aggressively returned, Dulin decides it’s the perfect time for one last adventure: a week-long bus tour of North America’s Impossibles, the physics-defying glitches and geographic miracles that started cropping up seven years earlier—right after the Announcement that revealed our world to be merely a digital simulacrum. The outing, courtesy of Canterbury Trails Tours, promises the trip of a (not completely real) lifetime in a (not completely deluxe) coach. Their fellow passengers are 21st-century pilgrims, each of them on the tour for their own reasons. There’s a nun hunting for an absent God, a pregnant influencer determined to make her child too famous to be deleted, a crew of horny octogenarians living each day like it’s their last, and a professor on the run from leather-clad sociopaths who take The Matrix as scripture. Each stop on this trip is stranger than the last—a Tunnel outside of time, a zero gravity Geyser, the compound of motivational-speaking avatar—with everyone barreling toward the tour’s iconic final stop Ghost City, where unbeknownst to our travelers the answer to who is running the simulation may await.
