Iris Wildthyme, Series 2, 5: The Claws of Santa (Unabridged)

Description of book

It's going to be a blue Christmas for Iris Wildthyme. Her best friend, Panda, is lost in time and space and the only festive cheer she can find is at the bottom of a glass. If that wasn't enough, this year's number one toy is trying to kill her!
From a futuristic planet-sized shopping mall to the frozen wastes of the North Pole, the search for Panda leads Iris to a fiendish plot that threatens to ruin Christmas for the entire multiverse. With only a jobsworth security droid to help, Iris turns to the one man who can save the season of goodwill - Saint Nick himself. There's just one snag; Santa Claus is a broken man...
With psychotic elves, exploding shoplifters and more tinsel than you can shake a bottle of Babycham at, this is going to be the Mother of all Christmases - and you're all invited!
