Amy, or Therese as she is known now, is the only survivor of a massacre which left her group of friends dead, twenty years later she is asked to attend a weekend getaway by a journalist with others with connections to what happened years ago.
Amy attends reluctantly but when all the attendees phones and and car keys disappear and one of the group is murdered it becomes clear that one of the party is intent on killing and Amy is in their sights.
This is a really satisfying locked room mystery with an impressive cast of characters - it is really well paced with plenty of twists - i really enjoyed it.

When Amy 'Therese' Brewer is invited to tell her side about a group of teens murdered twenty years before, she walks in to the weekend getaway to find a group of people with close connections to the massacre. The awkward meeting quickly turns deadly, but only after the group's phones and car keys go missing. One of the people in the isolated house is a murderer, and it's only a matter of time before they come for Therese.

Stacie Grey does an excellent job of drawing her cast of characters, giving them complex motivations and secrets, and compelling personalities. But the most impressive part is how Grey manages her twists; I've read quite a few 'murder in an isolated house/hotel/island' books, and Grey managed to take this one in directions I've never seen before, while still giving the reader the type of puzzle they expect. If you like twisty closed-circle murder mysteries, you'll love this book.

Thanks so much to the author, the publisher, and NetGalley for allowing me to review this ARC.
