Based on an original screenplay by Jeff Lieberman.

Blurb:

PSYCHOSIS…

It started off as a great party – just eight of them in a ski-lodge in upstate New York. But then the last guest, Frannie, arrived. There was something wrong with Frannie’s hair. And something very wrong with his eyes. And what he did with three of the girls was too hideous for description….
That was just the start. After that, things began to happen all over New York – ugly things: psychosis, insanity, murder – and no-one could find an explanation. The police were helpless- because they didn’t know that behind all the grisly happenings lay a single, uncontrollable horror. A horror called BLUE SUNSHINE…

For twenty-five years it grew in the shadows—tonight it waits for Amy in …  THE FUNHOUSE

A novel by Owen West based on a screenplay by Larry Block

Tonight Amy and her friends are spending the night at the carnival. And whilst they enjoy all the fun of the fair they will visit the funhouse, a place for gondola rides, gory delights and midnight terror.

But there is unspeakable Evil waiting for Amy in the dark labyrinths of the funhouse, a secret Evil that began twenty-five years ago, when a lonely woman destroyed her monstrous offspring, and a violently disturbed man vowed to exact his terrible revenge.

Now it’s Amy’s turn to keep her date with horror  as she enters the funhouse – for A CARNIVAL OF TERROR!

IT’S RAVENING, GUT- CHILLING, WORM-POWER — IN THE ALL-TIME HORROR CLASSIC!

Blurb:

“This was the night of crawling terror! SQUIRM is the blood-curdling shocker calculated to make you writhe with terror. A sleepy Southern town doesn’t know what’s hit it when a freak nightmare of a storm brings down the overhead electrical power lines which then direct a massive electrical charge into the wet mud. And that’s just the beginning. For the slimy, oozing, crawling horror which results – an angry rampaging mass of carnivorous superworms – is the most terrifying threat ever to be unleashed on (or under) the surface of the planet…”
