The Father Christmas Letters

 By J.R.R. Tolkien

This is a compilation of a few of the letters that Tolkien wrote to his nephews and nieces while pretending to be Father Christmas.  There aren't many letters, and they're mostly interesting for Tolkien fans, not so much for little kids.

 The pictures are delightful.  It's really sad that not all of the letters were published.  Probably because some of them were lost.

At one point Father Christmas has a war with goblins and learns the goblin language.  The goblin alphabet is in the back of the book.  Kind of interesting.
