A Killer Wedding

Description

*A NATIONAL BESTSELLER*

“Fans of The White Lotus and Knives Out will gobble up this whip-smart whodunit.”–Marie Claire

“A gripping whodunit in the vein of Agatha Christie, A Killer Wedding will keep you guessing until the final, shocking twist.” –Liv Constantine, New York Times bestselling author of The Last Mrs. Parrish

Wildly witty and wickedly fun, A Killer Wedding is an escapist mystery that proves you’ll never forget your wedding day…especially if it starts with a murder.

Editor Christine Russo can’t believe her luck. She’s been chosen by the iconic Gloria Beaufort, founder of a billion-dollar beauty empire, to cover her grandson’s wedding for Bespoke, the elite fashion magazine read by every A-lister.

It feels too good to be true…Because it is. Gloria is found dead on the first morning of the celebratory weekend, and her entire family wants to keep her death a secret and for the wedding to march on. When Gloria’s heirs issue a chilling warning to Christine to keep things quiet, she can’t help but wonder if one of them is guilty of murder. As she navigates a world where glamour masks grimy secrets and everyone she meets is a suspect, she realizes that among this glitzy elite nothing is as it seems.

Entertaining and compulsively bingeable, A Killer Wedding is a juicy page-turner that pulls back the curtain on toxic family dynamics hidden beneath the surface of billionaire-level wealth.
