Dean Koontz kicks the holiday season into high gear with a wildly inventive and wickedly funny sequel to his perennial Christmas bestseller Santa's Twin.

The Claus family's bad seed, Bob, is back and dishing out a second helping of holiday havoc and headaches for his twin brother, Santa. Exactly a year has passed since Bob kidnapped Santa and visited Charlotte and Emily in his stead, bearing gifts of mud pies, cat poop, and broccoli. After his defeat at the hands of the two brave sisters, Bob has worked hard to redeem himself in Santa's eyes.

Unfortunately Bob's spare time has been spent secretly building a robot Santa Claus. Super Santa One was designed to help Santa halve his delivery time, but Bob has left a screw loose on his creation (several screws, actually), and this Christmas Eve, a badly malfunctioning robot Santa Claus is coming to town.
