Dean Koontz has built one of the biggest careers in modern fiction on a very specific blend: supernatural dread, scientific paranoia, and a relentless pace that never lets up. Once you have burned through his back catalogue, it can feel like nobody else scratches quite the same itch. The good news is there is a whole shelf of authors who share his DNA, whether that means a shared genre, a shared influence, or in a couple of cases, Koontz's own words of praise on the cover.
Here are 10 authors worth picking up next, along with their three most popular books.
1. Douglas Preston & Lincoln Child
If you like Koontz's blend of scientific plausibility and supernatural dread, the Pendergast series delivers the same mix with an FBI agent instead of Koontz's usual everyman heroes.
