Book description:

You survived 25 Days. Now brace yourself for the nights.

Last December, readers followed an innocent family as they became pawns in a horrifying game of Secret Santa in Per Jacobsen’s international bestseller 25 Days.

This time around, the story dives deep into the mind of the villain; the man in the ski mask.

And what’s in there will not only offer a new perspective on the events of the first book—it may just change your view of him.

Once again, the rules of the game are simple:
25 Nights. 25 chapters. One for each day in December as you count down to Christmas.
