What I really love about this book is it's "scientific" look at Santa Claus and his mission. The illustrations and photographs are amazing and the work put into the realism is amazing and wonderful.

My only quibble with this book is the history they present of Santa himself. I am more fond of the traditional Saint Nicholas origin than the "Santa as an ancient elf" story they present here. I am also not fond of the sleigh design they present.

Other than that, this is a fabulous book.
