Booky Advent Calendar Day 18: "Hamish and the Terrible Terrible Christmas" by Danny Wallace and Jamie Littler (Simon and Schuster Children's Books)

Day 18 of our Booky Advent Calendar and we're ensuring that older kids get a look-in as well, with another fantastic middle grade book to tempt you during the festive period.

"Hamish and the Terrible Terrible Christmas" is a special festive-flavoured outing for Danny Wallace's reluctant hero.

Hamish soon discovers that even though every single shop is playing "Merry Christmas Everybody" by Slade, and all the ad breaks are showing holiday or rotten perfume ads, the task of saving the world hasn't gone away just because there's a smattering of snow on the ground.

In this three-story compendium, Hamish Ellerby and his friends in the PDF will have to deal with rotten sweetie salesmen with a hidden agenda, unexpected christmas eve visitors (don't you just HATE those!) and some nefarious creatures who want to put Starkley on the map - of DOOM!

Written in Danny's blisteringly paced and brilliant humour (psst, don't tell David Walliams but C actually prefers Danny's books to his!) this is a christmas corker that's even better than an ugly christmas sweater in the 'coolness' stakes.
