The Guest List by Lucy Foley
This thriller has one of the my favorite novel settings ever - a remote island off the coast of Ireland (I spent a year in Ireland studying creative writing after college). The bride, magazine publisher Jules Keegan, is marrying a tv star in a lavish wedding that has spared no expense. As a storm brews and the point of view shifts between Jules, the best man, the wedding planner, the bridesmaid, and the wife of Jules' best male friend, we learn that something tragic is about to take place during the reception - and the groom is not the man anyone thought he was.
Why I Loved It: This is the kind of book you want to cozy up with under the blanket on a rainy Friday night. Perfectly plotted. A thrill to read.
