Recs if you like Seven Bodies: A brand new locked-in murder mystery...

... You're trapped here with me! The format: A group of people (could be strangers, or long-lost friends) are gathered or trapped in an isolated place together. Maybe it's a remote island. Maybe a cozy cabin during a blizzard. Someone is killed. The killer is obviously among them, but who?! Submissions welcome because this is my favourite mystery sub-genre at the moment, and I can't wait to discover more!

A silly little collection of a trend I've noticed recently, usually among thrillers. Some of these probably have alternate covers as well, but I'm including them because I've seen one which fits. Suggestions welcome! Simply ask yourself: Is house blue? Is window yellow?
