Four girls close their eyes. Only one wakes up.

Leah and her three best friends get changed into their pyjamas, eat pizza and argue about what film to watch. They laugh together until the early hours. But the next morning, Leah blinks open her eyes and sees three empty sleeping bags. The other girls are gone.

Twenty years later. In her small hometown, still-haunted Leah has never been able to shake off the rumours and whispers. How could she have slept through it all? She must know what happened.

Now, a documentary is being made about the night Leah’s best friends disappeared. Is the truth about to come out?

Then an anonymous email arrives in Leah’s inbox. ‘Stop them’.

Somebody out there knows what happened the night of the sleepover. Is Leah in terrible danger? And will she ever find her missing friends – or are some secrets meant to be kept forever?

An absolutely addictive psychological thriller with twists and turns that will make you gasp. Anyone who loves Lisa Jewell, Shari Lapena or The Perfect Marriage won’t be able to put this down.
