When a Lesley Kinnock buys a lottery ticket on a whim, it changes her life more than she could have imagined . . .

Lesley and her husband Mack are the sudden winners of a £15 million EuroMillions jackpot. They move with their 15-year-old daughter Rosie to an exclusive gated estate in Buckinghamshire, leaving behind their ordinary lives - and friends - as they are catapulted into wealth beyond their wildest dreams.

But it soon turns into their darkest nightmare when, one beautiful spring afternoon, Lesley returns to their house to find it empty: their daughter Rosie is gone.

DC Maggie Neville is assigned to be Family Liaison Officer to Lesley and Mack, supporting them while quietly trying to investigate the family. And she has a crisis threatening her own life - a secret from the past that could shatter everything she's worked so hard to build.

As Lesley and Maggie desperately try to find Rosie, their fates hurtle together on a collision course that threatens to end in tragedy . . .

Money can't buy you happiness.
The truth could hurt more than a lie.
One moment really can change your life forever.
