This is one of the Alan Durant 'letter' collection - books written about a young girl called Holly and her pen pal relationships with various hard to find friends ie the Tooth fairy, Mermaids and in this book, Father Christmas. There are little letters to pull out of every other page, often with little gifts too - there is a card Father Christmas cut out to hang on the tree and a miniture advent calendar. Not as good as Dear Mermaid, where I think the humour and gifts were better, but still a really good buy for the festive period, lovely to read as a bed time story on the nights bulidng up to Christmas.
