You Better Watch Out, the brand-new sinister and addictive YA thriller by Costa-shortlisted Sarah Naughton, is out now.

You Better Watch Out… You better not die.

Everyday 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 the 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?

Dark, moreish and chilling—the countdown to Christmas is on… and time is running out.

You Better Watch Out is out now. Grab your copy here or, better, via your local bookshop or Bookshop.org.
