This is technically a short story. It's by the author of Gone Girl and from reading all her books, I can honestly say, you never know where this author is going to take you. I read this book in one sitting. You can read it in a little over an hour and it's pretty good...it doesn't "wrap up" in the end. You draw your own conclusions but even in 62 pages, I was like "wow, didn't see that coming".
Gillian Flynn’s Edgar Award-winning homage to the classic ghost story, published for the first time as a standalone
A canny young woman is struggling to survive by perpetrating various levels of mostly harmless fraud. On a rainy April morning, she is reading auras at Spiritual Palms when Susan Burke walks in. A keen observer of human behavior, our unnamed narrator immediately diagnoses beautiful, rich Susan as an unhappy woman eager to give her lovely life a drama injection. However, when the "psychic" visits the eerie Victorian home that has been the source of Susan’s terror and grief, she realizes she may not have to pretend to believe in ghosts anymore. Miles, Susan’s teenage stepson, doesn’t help matters with his disturbing manner and grisly imagination. The three are soon locked in a chilling battle to discover where the evil truly lurks and what, if anything, can be done to escape it.
