Santa's Twin

by Dean Koontz

1995

Two sisters discover Santa has a mischievous twin, Bob Claus, who steals the sleigh and fills the toy bag with disgusting surprises. They fly to the North Pole to rescue Santa and save Christmas from turning into a prank.

Series background & context

The Santa’s Twin books are Koontz in kid-friendly, read-aloud mode: silly, mischievous, and built around the idea that the North Pole has its own troublemaker. Santa’s twin brother, Bob Claus, is jealous, impulsive, and convinced he’d be better at the job.

In Santa’s Twin, Bob takes over Christmas and turns it into a gross-out prank, forcing two sisters, Charlotte and Emily, to step in and set things right. The sequel, Robot Santa: The Further Adventures of Santa’s Twin, raises the chaos by adding a robot helper that doesn’t behave like anyone planned.

These are quick, goofy stories with a simple message: kindness beats selfishness, and even bad behavior can sometimes be corrected with a little courage and a lot of heart.

Holiday chaos, not holiday horror.

Read them in order for the best fun, starting with Santa’s Twin.
