The Guest List

The Guest List is a 2020 mystery novel by British author Lucy Foley, set on a remote island off the coast of Ireland. The story unfolds during the wedding of Jules Keegan and Will Slater, where a murder occurs and each guest harbors a secret. The plot has been compared to the works of Agatha Christie, with limited suspects and a storm that cuts off the island from the mainland.

Through alternating perspectives of key characters—including the bride's half-sister Olivia, guest Hannah, best man Johnno, and wedding planner Aoife—long-buried secrets surface. The narrative shifts between the wedding day and flashbacks, revealing past traumas and connections that lead to a shocking climax. The novel became a New York Times, Sunday Times, and Washington Post bestseller, selling over a million copies in 30 territories.
