HIDEOUS NIGHT is the novel-length sequel to The Valley Of The Shadow in my short story collection—DOMAINS OF DARKNESS.
Marius Larsen is convinced that the race of human parasites known as The Hran are real and are a terrible danger. But no-one believes him.
In the meantime, the brilliant scientist Celine Dubois has her own problems: people are disappearing from her research facility. It looks like some unknown power is harvesting them.
Eventually, she discovers the secret behind the vanishings but in so doing she finds that the Hran are all too real and that she and Marius Larsen are the only hope of ridding humanity of this horrific scourge.
