"The Cabin" by Natasha Preston. My rating: 3 out of 5 stars. Published in 2016.
Book description: There may only be one killer, but no one is innocent. They think they're invincible. They think they can do and say whatever they want. They think there are no consequences. A weekend partying at a remote cabin is just what Mackenzie needs. She can't wait to let loose with her friends. But a crazy night of fun leaves two of them dead-murdered. With no signs of a forced entry or struggle, suspicion turns to the five survivors.
In general, when deciding to read a book, I rarely look at reviews, but I do find it interesting that, this time, my rating mirrors the average rating by other readers.
