The perfect weekend away. A remote lodge, old friends - and murder. It's been twenty years since they were all at school together. So when a group of female friends gather at a beautiful but isolated Scottish island lodge for a weekend away, they're looking forward to relaxing, sharing updates on their lives, and reminiscing. The furthest thing from their minds is murder. But even though they've known each other since high school, some of these women have secrets. Dark secrets that can ruin friendships, ruin marriages - ruin lives. Things you thought you knew and loved can turn out to be your biggest nightmares. And when recriminations start to fly, it soon becomes clear: it's not a question of when, but if, these old friends will ever make it home again.
