They all had a reason. Only one had the nerve.

Twenty years ago, student Daisy Harrington went out for the evening and never came home. Her body was found a week later. The killer was caught. Case closed.

Now, on what would have been her fortieth birthday, her five university housemates are invited to a weekend gathering. None of them want to go. But none of them can refuse—the invitation makes it clear that if they don’t attend, the past they’ve spent two decades hiding will finally come to light.

Because the man convicted of Daisy’s murder was innocent. And one of the five has known this all along. As the weekend unfolds, the truth threatens to finally be revealed…

They all wanted Daisy dead, but one wanted it more. The question is…who? And why?
