"Your friend's child. Your responsibility. Your fault." -- Cover.

What if your best friend's child disappears? And it's all your fault... This is exactly what happens to Lisa Kallisto - overwhelmed working mother of three - one freezing December in the Lake District. She takes her eye off the ball for just a moment and her whole world descends into a nightmare. Her best friend's thirteen-year-old daughter Lucinda has gone missing and now, devastated by this and publicly blamed, Lisa sets out to right the wrong. But as she begins peeling away the layers surrounding Lucinda's disappearance, Lisa learns that the quiet town she lives in isn't what she thought it was, and her friends may not be who they appear to be, either.
