The Apocalypse Door, James D. Macdonald (2002)
Just plain fun. A hardboiled spoof featuring Knights Templar secret agents and the Special Action Executive of the Poor Clares (who “tend toward the simple life: knives, garrotes, and gunfire”). Gore, explosions, car chases, exorcisms, time travel, and a lot of Last Rites.
Nova Swing, M. John Harrison (2006)
Not half as good as the transcendent Light, but still worth it for Harrison’s extravagant prose. Atmospheric, hallucinogenic noir; various characters (some from Light) meander, cross paths, solve crimes, and drink a lot in the city of Saudade, which borders on the mysterious “event site”. Also, there are cats.
