#1 NEW YORK TIMES bestselling author Natasha Preston is BACK with another gripping, edge-of-your-seat thriller. Perfect for fans of Karen McManus and Holly Jackson.

WHAT HAPPENS WHEN YOU ARE HOME ALONE AND RECEIVE SINISTER MESSAGES ONLINE?

Sixteen-year-old Connie has been dragged into the world of vlogging - her mum Lou's vlog is hugely popular, enough to bring in enough money for a new house, expensive lifestyle . . . and a lot of criticism.

While Lou and Connie's older sister Isla are touring colleges for a new vlog, Connie stays home alone, where she becomes increasingly paranoid about comments on the vlog. Plus someone is turning up at her school and following her on her way home.

Then Connie's best friend is attacked - the third teenage girl attacked in five weeks - and suspicion turns to Connie. Connie doesn't know who she can trust any more and goes on the run. But will the killer - whoever they are - catch up with her?

Another terrifying, twisty thriller from the queen of surprise endings, Natasha Preston.
