Daisy and Frank’s wedding is set to be the event of the year: a lavish weekend in a remote French chateau, where a group of university friends will reunite for the first time in years.

The champagne is flowing, the setting is perfect and the guest list is… deadly. When a latecomer joins the weekend’s festivities, their arrival turns more than one guest’s blood cold...

A face from the past. A friend they all thought they’d lost forever. A friend that they believed to be dead.

As the weekend unfolds, long-buried secrets are uncovered and the truth becomes impossible to ignore: someone has brought this guest back for a reason.

It’ll be a weekend they’ll never be able to forget. No matter how much they’ll want to.
