Prepare for your latest obsession....

The addictive new thriller from the Sunday Times bestselling author of Friend Request.

Sasha North has gone missing.

Everyone says she's run away, but I know better. We've been best friends since we were teenagers, since Sasha swept into the neighbourhood and brought colour to my life. Until a brutal attack changed both our lives forever.

I know what happened that night. I know who wants revenge.

And if Sasha has been taken, does that mean I'm next?
