Dell/Abyss line were making obsolete. Still, I decided to take a chance since it has a bunch of rave reviews on Amazon. Maybe an overlooked classic? Er, no.
The small, foggy Washington town in Puget Sound is beset by evil and its everyday American citizens have been disappearing for months, leaving no trace behind. It's up to a regular cast of characters, some noble, some embittered, some doomed, to do battle against an ancient enemy whose evil knows no bounds...
PS. Finally I've figured out the font on the edition at top; it's ITC Benguiat. Designed in 1977, it was used on all kinds of paperbacks throughout the '70s and '80s, and has always been a favorite of mine.
