The Guest List by Lucy Foley

Great mystery! A wedding on an island, the guests full of secrets and grudges... what could go wrong? Throw in spotty cell service, a storm, lots of alcohol and you have yourself a page turner! It was suspenseful while also being funny—especially if you’ve ever planned, or been in, a wedding.

The novel jumps from a couple POVs but Foley makes it work. The groom is a reality TV star and the bride publishes a magazine. You also follow the wedding planner, the best man, the bridesmaid, and the plus one. Who dies? Who’s the killer? You're kept guessing until the very end.
