This is a short story by Gillian Flynn that has recently been published in its own hardcover book. I picked this book up because a reading challenge I am doing has "a book that is less than 150 pages" and Gillian Flynn is a unique and phenomenal writer. I was not disappointed! I am not in love with this story as her other ones, but I read it in one sitting and was glued to the pages from page 1 until the end. If you like Gillian Flynn then this is a good, one sitting read!
