The Wedding Thriller Genre
Foley’s success (after 2015’s The Hunting Party) sparked wedding-set thrillers: The Guest List formula of toxic friendships, dark secrets, and island isolation became a template for 2020-2022 releases.
Why It Resonated
The novel’s examination of Instagram-perfect weddings hiding dysfunction resonated during early pandemic when weddings were canceled/postponed. The multiple POVs created unreliable narrators and “spot the killer” reader engagement.
