The beautiful bride
Annie never believed in true love. Not until she caught sight of Mark on a crowded commuter train. It wasn't until months later that they finally had their picture-perfect first date and after a whirlwind romance, they are now about to tie the knot.

The handsome groom
Both Annie and Mark have suffered tragedy - their shared experience of sorrow has brought them together, but at times the pressure of those losses has also threatened their happiness. Today they will leave all of that in the past, and forge a new life. But not everyone gathered here has come to toast the new couple.

The stranger
And Annie quickly realises that her new life isn't going to be the happily ever after she had planned.

A completely unputdownable, brilliantly sharp, dark and twisty story of love, lies and obsession that is set to be one of 2024's most talked about debuts.
