Desperation - Stephen King 1996 - The Regulators by Richard Bachman
1996 - Desperation by Stephen King

These 2 were meant to be companion books by King using as they did the same character names, in a similar sort of peril from the same monster. A lot of reviewers said it was lazy writing at the time but I personally loved it. It added rather to my enjoyment of both rather than detracting.

Good Times.
