The Naughtiest Reindeer by Nicki Greenberg

'Santa, are you kidding? You want RUBY to help pull the sleigh? Ruby?'

Ruby's the naughtiest reindeer in the entire North Pole! Just ask Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner and Blitzen. They know that Ruby is going to bring a whole stack of mayhem this Christmas.
But she just might deliver some surprises as well.

A cheeky and charming celebration of the Christmas spirit.
