While real-world horrors and a general disinclination toward reading might make Halloween book recommendations obsolete, here are my assorted indie horror books that I'm nearly certain you've neither heard of nor particularly care to read, but I feel obliged to share anyway:

NOVELS

The Wolfshadow Trilogy

SAAMAANTHAA
THE HAPPENING
NORM

One of the best almost completely disregarded werewolf trilogies out there, in my opinion. The kind people will discover a decade or two after I'm dead and decide they really liked it. A nice time capsule for a lost America and also a portent of the nightmare to come.

CHOSEN

My purest horror novel, being a neo-Lovecraftian take on a zombie apocalypse, set in Pennsylvania. Even more completely disregarded than Wolfshadow, amazingly enough.

SUCKAGE

My Chicago-based vampire minion novel, which never found its audience, so it's another nearly completely ignored effort that I still think holds up, especially for those readers who don't want sparkly vampires.

THE CURSED EARTH

My Pennsylvania-based cosmic folk horror novel that manages to both honor and lampoon those subgenres. I greatly enjoyed this one, think it's my best horror novel, but, of course, was woefully ignored. Maybe someday people will discover and appreciate it. Or not.

RETURN TO SUMMERVILLE

The sequel nobody really asked for, so I suppose I shouldn't be surprised at how thoroughly disregarded this one was. I thought I revisited the titular setting in grand style, making a sequel that exceeded the original novella.
