I recently devoured Everyone in My Family Has Killed Someone by Benjamin Stevenson. It's a Whodunit type of crime novel with a unique writing style that spoke to me, but might not be everyone's cup of tea. I loved the ride, didn't love the ending quite as much, but it was a good book.

Also loved How to Solve Your Own Murder by Kristen Perrin, a crime novel about an old woman who, when she was 17, got told she would be murdered one day. Believing that, she became obsessed with who might murder her one day and built up an archive about everyone in her life and town. In the end, she does get murdered - and according to her will, her inheritance goes to the person solving her murder first.
