A pleasant little sister volume to the earlier one that showed what teachers would never, ever say at work – this one doesn't really subvert the idea of Christmas, because what it says Santa would never do is just that – fail his sleigh-flying licence, get lost, get Xmas and Easter muddled up... As a book it's alright for Christmas, but if it gets read at all after Jan 1 it might be a minor miracle. It also has a very cheesy moral kind of conclusion, to try and shoe-horn it into the gift market. Despite there being little wrong with it, it may struggle.
