We absolutely adore the "Katie" books and James Mayhew pulled out all the stops with his special Christmas story, a whirlwind adventure for Katie and her cousin Jack in "Katie's London Christmas".
Katie and Jack are startled by a loud...
"ATCHOO!"
When they go to investigate, they find that poor Father Christmas has a rotten cold, and could really do with a couple of helping hands to ensure everyone gets their Christmas Pressies well in time for the big morning.
So it's a hop, skip and a jump into Santa's sleigh, for a trip across the London rooftops, taking in the landmarks as they go and - with a little festive magic - squeezing down the chimneys to deliver lovely christmas gifts.
Watch out for the "Scarf" bit :)
"Katie's London Christmas" by James Mayhew is out now, published by Orchard Books.
