answer: Their story is riveting, appalling, and highly readable.
paragraph_question: question: How fascinating is the book?, context: Welcome to the world of Amy Elliott Dunne and her husband Nick Dunne.  On their fifth wedding anniversary, a day Amy always celebrates to the hilt, she disappears under mysterious circumstances.  Nick is the prime suspect and does nothing to make his family, the media, or the public think differently.  Thus begins a highly suspenseful tale loaded with twists and turns to keep you eagerly turning the pages.  I am in awe of author Gillian Flynn's clever plotting and now anxious to read her two previous books.  To go more deeply into the story line would involve spoilers, so I will avoid that and just say Amy and Nick are two of the most dysfunctional, psychotic people you may ever come across.  Their story is riveting, appalling, and highly readable.  A smart and stylish golden couple who complete each other in every way, their story and the inside look into their marriage will have readers mesmerized from romantic beginning until the stunning finale.
