What’s it about?

The story.

Lottie Brooks loves Christmas, but this year the festive season is even more chaotic than usual. The whole extended Brooks family is descending for the holidays (plus a few surprise visitors), there's a school Secret Santa to survive, and the family hamsters simply will not stop attacking Gavin, the Elf on the Shelf. Between a disastrous garden-centre Santa photo where baby Bella bites the poor man's nose, the annual mortification of the school nativity, and the horror of being caught in a novelty turkey hat, Lottie has her hands full, all while quietly navigating her sweet first romance with Daniel. Told in Katie Kirby's diary of doodles, dynamic fonts, text threads, thoughts of the day and endless lists, this Christmas instalment of the bestselling Lottie Brooks series is a cosy, riotously funny celebration of the small catastrophes that seem to find Lottie wherever she goes. A perfect festive read for fans of Dork Diaries and Diary of a Wimpy Kid.

Why they love it.

Why kids love it

A baby biting Santa's nose, hamsters ambushing the Elf on the Shelf and a novelty turkey hat catastrophe make this the funniest festive diary going. It's stuffed with texts, lists and doodles about everything that goes gloriously wrong at Christmas.

  • Cosy safety
  • Friendship and belonging
  • Being understood finally
  • Family belonging

Why parents love it

Warm, silly and reassuringly gentle, it's the ideal Christmas gift or stocking book for a tween. The family chaos is affectionate rather than mean, reluctant readers race through the diary, and there's plenty of shared humour for the adult reading along.

  • Shared humour
  • Quick to read
  • Bedtime appropriate
