Emma Carter trusts evidence. She trusts logic. She trusts everything that can be proven.

Until a wedding invitation arrives from the woman who disappeared seven years ago.

Iris White was Emma's closest friend in college. After vanishing without a trace, Iris was declared gone forever. No body was found. No answers remained.

Then Emma receives an invitation bearing Iris's name.

The wedding location does not exist on any map.

But when Emma follows the address into the fog, she finds an old church waiting beneath the lights. Inside are the guests—silent, dressed in forgotten formal clothes, and impossible to ignore.

Because they are all dead.

Among the faces in the church are people whose deaths were recorded years before. And sitting at the front is someone Emma never expected to see again.

Iris.

She claims this is not a wedding for the living. It is a ceremony with rules. A tradition that has continued for decades.

And according to the guest list, Emma is the final name waiting to take a seat.

The closer midnight approaches, the more Emma realizes this is not about attending a wedding.

It is about discovering why she was invited.

And what will happen when the last living guest arrives.
