Owen West [Dean R. Koontz] – The Funhouse (Sphere, 1981)
Blurb:
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!
