The Sleepwalker by Chris Bohjalian

Absorbing story of a family reacting to the sudden disappearance and presumed death of the wife and mother. The twist is that she suffered from sleepwalking (parasomnia) -- so the reader learns a lot about this topic throughout the course of the narrative. 

What happened? Beautiful Annalee Ahlberg vanished after apparently walking out of her home in the middle of the night. The story is basically a family drama with a mystery that is told from the point of view of the oldest daughter, 21-year-old Lianna, who is trying to take care of her younger sister Paige and her father, Warren.

I found the information about parasomnia quite fascinating as it is not something I knew much about beforehand. However, I didn't care much for any of the characters in the book, I didn't relate to Lianna, and was quite disappointed in the ending when the mystery is solved. I did not find it suspenseful or "spine tingling" and would not say it is a thriller. I would say this is not my favorite Bohjalian novel and I have read all the previous ones so just making that comparison. Others may certainly find it more "mesmerizing" than I did.

Thank you to Edelweiss and Doubleday Books for the e-book ARC to review.
