This list includes classics, contemporary, childrens, spin-offs / retellings etc.
First we have Cold Spell by Jackson Pearce which is a retelling of "The Snow Queen" by H.C. Andersen (which is another story you could read). This is tecnically the 4th in a series, but since it is only a "companion" series you can read this as a standalone - if you like.
Then we have Dash & Lily's Book of Dares by Rachel Cohn and David Levithan. I read this in February and I had to give it 5 stars because I seriously enjoyed it. It is set during the Wintertime and it has a sweet romance in it. AND BOOKS.
Let it Snow by John Grenn, Lauren Myracle and Maureen Johnson is another cute christmas book which contains 3 holiday romances. I can honestly say that John Green is the only reason why I bought this book, and I cannot wait to read it.
I love Dr. Seuss - The Lorax is my all-time favorite movie - so How the Grinch Stole Christmas is an obvious choice. It is such a light read and such a fun one too. I love reading it aloud and making funny voices for my baby brother.
A Christmas Carol and other Christmas books by Charles Dickens. I watched the adaptation with Jim Carrey in it back in 2009 and I loved it. Since then I have had an obsession with a Christmas Carol, so this is a perfect book since it contains other books by Dickens too. I believe there a 5 in total.
I am Scrooge: A Zombie Story for Christmas. I found this a while back and I thought it was such a weird idea that I just HAD to buy it. So apparantly zombies are in for Christmas too!
Claus: The Legend of the Fat Man by Tony Bertauski. A book about SANTA! I think this has another angle on the whole Santa-thing, but I am not sure.
The Holiday Collection from the Indie Eclective. A bunch of short Christmas stories wrapped in one FREE EBOOK.
Twas the Night before Christmas and other Christmas Stories. This contains about 30 different stories about Christmas (it also contains A Christmas Carol)
