This was not a good read for me. For fans of destination wedding/locked door mysteries, you are better to go with Lucy Foley’s The Guest List.
This books seemed like a fun idea, and then it lost its identity and attempted to add other subplots to make a richer, fuller story. All it did was make more incomplete and unnecessary stories crash into each other and leave you unsatisfied. Pick one story and tell it well. That’s all I ask.
