If you haven't already read it, I highly recommmend adding "A Cup of Christmas Tea," by Tom Hegg, to your holiday book collection.
I read this every year, as we get very close to Christmas. It's a story about a guy who reluctantly decides to visit his elderly and infirm aunt during the holidays.
As he visits, he remembers all of the things that were once important when he was younger, through his chat with his aunt and the holiday decorations she has everywhere.
My favorite lines from the book, and the ones that usually sets me to crying, are:
We went inside and then before
I knew how to react
Before my eyes and ears and nose
Was Christmas past, alive, intact!
I haven't read it yet this year, but will any moment now, with a warming cup of tea beside the glow of the Christmas tree, as snow falls quietly outside.
