Fiction by Harlan Coben.
There is a book by Albert Camus with this same title I read in high school.
This book is not a classic novel like that one. This is what scholars like my high school English teacher would call a "popular novel," possibly while holding it with two fingers and snorting derisively.
Although I don't think Ms. West will be assigning any Harlan Coben novels anytime soon, this was a great story! I loved the plot twists in this book. And I don't mind being a lowbrow reader.
My apologies to Camus: your book was really good too!
I also read recently by this author: Fool Me Once.
