In a taut locked-room mystery from New York Times bestselling author Kieran Scott, a group of longtime friends confronts their darkest secrets—and deadliest impulses—on the brink of a hurricane. For years, three couples have gathered at The Villa—billionaire Lincoln Foster’s Hamptons estate—for lavish weekends among friends. But this year, mysterious blue cards appear in each bedroom, exposing secrets: their host’s betrayals and the guests’ own dark deeds. Everyone has something to hide. Marley and Marshall Foster. Suzy and Sean McTeague. Juliet and Josh Jacoby. Lincoln and his new wife, Hazel. Even uninvited guests hoping to be accepted among the elite. With a hurricane bearing down, no one is getting out. When the revelations turn deadly, the trapped friends must confront what their lies have cost them—possibly their lives.
