Dark, moreish and chilling - the countdown to Christmas in on ... and time is running out.

Every day in December, a gift is left for Eleri in the abandoned tower block opposite her flat.

At first, she can't help but be flattered, hoping that her Secret Santa is enigmatic Ras - a boy she has history with.

But with each day that passes, the gifts get darker and more dangerous. Is this a harmless bit of festive fun? Or does this have something to do with Nina's disappearance last year? If so ... will Eleri be next?
