Ten years ago: On a warm summer’s evening, four childhood friends gather at a slumber party.... Before dawn breaks, the nightmare begins. One of them dies. One of them is a killer.

Liz was the bubbly girl next door. She could never have imagined how everything would fall apart.

Sami was the clever one, quieter than the others. She was meant to keep all their secrets....

Amy had the voice of an angel, destined for Hollywood. She would never make it there.

Mo was leader of the group, charismatic and protective. But she was not who she appeared to be....

They were childhood friends, on the cusp of the rest of their lives. They’d shared everything with each other. Or so they thought.... Until one of them died.

Today: Liz tries not to think about the night that destroyed their lives. She focuses on her beloved husband and their sweet-eyed daughter. But when she receives a note, there’s no more running away: “I’m back. Did you miss me?”

A wave of dizziness crashes over her. Her best friend can’t be back. She’s dead. So who sent the note? What do they know? And, most terrifying of all, are they planning to make her pay for what happened?

A totally gripping, heart-stopping thriller about twisted friendships, dark pasts, and secrets to die for.... If you love The Night She Disappeared, Girl A, and The Housemaid, you’ll love The Slumber Party.
