Let's start with a good thriller/suspense.

The Silent Patient by Alex Michaelides: Alicia Berenson’s life is seemingly perfect. A famous painter married to an in-demand fashion photographer, she lives in a grand house with big windows overlooking a park in one of London’s most desirable areas. One evening her husband Gabriel returns home late from a fashion shoot, and Alicia shoots him five times in the face, and then never speaks another word.

At the end of the evening, each member can submit their choice for the next read.
