Books of December Part 1:

 Supernatural: The Official Cookbook: Burgers, Pies, and Other Bites from the Road by: Insight Editions

Non-Fiction: Food, Pop Culture, 128 pages

This book was, as one would expect, written before the end of the show.  But as it is largely about the food that has been eaten in the series this has little effect on it.  It is divided up into types of meals, foods, etc. For example, breakfast, burgers, and pies.  For each recipe it includes info on why it is in the book.  This could be an episode, a food that is eaten a lot overall, or something that a character likes.  It also had many pictures.

A Thyme and Place: Medieval Feasts and Recipes for the Modern Table by: Lisa Graves, Tricia Cohen

Non-fiction: Food, History, 152 pages

1st, while the book is based off of recipes from the middle ages to slightly after the renaissance the recipes have been updated for modern ingredients and cooking methods, sometimes with info on what was originally used.   2nd, this book only deals with English holidays and foods. 3rd, this book follows the formula that the "church" is a singular thing that hated fun, and so will range from talking about the Catholic Church to the most Puritan Calvinist with no note about them being very different groups. (which results in confusing statements if you didn't know which they were talking about, like when outlawing Christmas or pie.)

 The Haunting of H. G. Wells by: Robert Masello

Fiction: History, Mystery, Paranormal, E-book

This story takes place during WWI and as one expects stars H.G. Wells.  It deals with him going to the front for the war effort, and seeing the real horrors of war.  It also deals with a moral quandary his wife has back at home,  And a female reporter, who likes Wells and her chasing a story.  Of course all these connect to the biggest issue in the story.

 Christmas Miscellany: Everything You Always Wanted to Know About Christmas (Books of Miscellany) by: Jonathan Green

Non-Fiction: History, Holiday, E-book

This book also mostly deals with Christmas traditions in the UK, but also deals with general Christmas traditions and info about ones for other places. (Mostly ones that were started in the USA.)  But this one is for the most part well researched and there are very few mistakes in it. There were a few things like plum used to mean any dry fruit, so plum pudding doesn't usually have actual plums in it. (And figgy pudding doesn't have to have figs, and they both are Christmas pudding.)  But besides a few things like that, it is full of information and history on things related to Christmas.
