Starred review from June 26, 2023
A drug designed by the military weaponizes people’s nostalgia in this sinuous and transfixing collaboration from Macdonald (H Is for Hawk) and Blaché. After an American roadside diner magically appears outside of a U.S. air base in England, the two operatives dispatched to investigate—former MI6 agent Sunil Rao and American intelligence officer Adam Rubenstein—trace its likely origins to Lunastus-Dainsleif, a lab in Aurora, Colo., that runs the military-funded Eos Prophet program. Prophet is a wildly unpredictable pharmacologic agent that induces material approximations of fond memories—referred to as Eos Prophet Generated Objects, or EPGOs—but at a grievous cost for the user: a psychic break, and sometimes death. Rao and Rubenstein prove immune to the side effects, which makes them the perfect agents to study the drug. The novel’s denouement, in which Rao, Rubenstein, and their ops team navigate a landscape booby-trapped with rogue EPGOs to rescue Lunastus’s CEO, is wildly surreal with occasional flashes of dark humor, such as a Pac-Man machine that physically consumes a man who was once addicted to the game. The authors’ most irresistible achievement, though, is their odd-couple pairing of the Dionysian Rao with the fastidious Rubenstein, who bicker and banter contentiously despite their fondness for each other. The well-matched authors make good on their audacious premise.
