The Nightwalker

When Gillian Norlund learns of her brother Robin's request to reunite her with her estranged father, she returns to Clairemont, the family estate, with some reluctance. It was there, in days long past, she had experienced a rejection by her family. When Gillian and her twin children arrive at the house, they find a mansion infused with trauma.

Gillian's sister Amanda is neurotic and obsessive, her half brother Robin is aloof then friendly. And something is causing terror in Clairemont, a terror which only Gillian can dispel - yet which threatens her more than any other with a vengeful, violent death.
