Two sisters go missing Only one returns. We believe what we want to believe. We believe what we need to believe. When my sister and I disappeared three years ago, they found Emma's car at the beach. Some people believed she had gone there to find a party or meet a friend who never showed. They believed that she'd gone for a swim. They believed that she'd drowned. Maybe by accident. Maybe a suicide. Everyone believed Emma was dead. As for me, well - it was not as simple as that.
