Domestic situations that go awry are common in the psychological suspense novels of Chris Bohjalian. In The Sleepwalker, Bohjalian examines sleepwalking (or parasomnia) and the devastating impact it has on a Burlington, Vt., family.
Narrator Lianna Ahlberg deconstructs events that took place when she was a 21-year-old college senior during the autumn of 2000. When her father, Warren, a professor, went away to a conference, she tended to her 12-year-old sister, Paige, and her mother, Annalee, who had a history of sleepwalking that included benign destructive behaviors--especially when Warren was gone. Annalee had been undergoing treatment at a sleep clinic, and it had been four years since she took a nocturnal journey. Therefore, Lianna's caretaking was merely a precautionary measure. Believing her mother was past the "witching hour" (the first three hours of sleep) and out of harm's way, she dozed off, only to wake the next morning and discover Annalee missing. As the family rallies to search for her, a piece of her nightshirt is found near a riverbank, and the mystery deepens when a detective working the case seems privy to eerie, intimate details about Annalee.
Bohjalian (The Guest Room) has written an absorbing, cerebral story that probes a family's haunted emotional response to the mother's disappearance, and how each copes with confusion and grief. As they plumb the depths of Annalee's life, they uncover secrets that ultimately reveal a startling truth. --Kathleen Gerard, blogger at Reading Between the Lines
