Helltown (World's Scariest Places Book 3) by Jeremy Bates

A group of young people visits Helltown, a small town legendary because of rumors of occult activity. What they encounter is a Satanic cult.
There's a large number of people being moved around the chessboard in this one. Some are evil, some a bit more heroic. It is fascinating to see how these chess pieces encounter each other.
The characters get enough depth to warrant their time on the page. The action scenes are horrific enough, though I wouldn't see it gets scary really.
Bates shines in introducing interesting characters with good backstories, especially the lone soldier whose role in the book stays unclear for a long time.
More of a slasher novel than occult horror which you might expect from the name of the book it will appeal to fans of Friday the 13th and stuff like that.
