Odd Apocalypse

A billionaire's estate turns out to be a deadly trap controlled by ancient, malevolent machinery — this is Dean Koontz's signature blend of supernatural horror and suspense rather than straight thriller territory; the 'oddity' (Odd Thomas himself) navigating a literal hellscape beneath the surface justifies paranormal/suspense over what might otherwise read as pure crime. The tone is tense and dark throughout but grounded in Odd's wry, fatalistic humor, so dark-humor fits alongside the darker moods.
