I read Dustin Thomason's book "12-21" last year, finishing it on 12/21/2012. Since the story deals with an apocalyptic disaster caused by an ancient civilization, I'd wanted to see if I could finish it before the pivotal date last year.It was a fun book, but it wasn't spectacular. I liked Thomason's theory concerning viruses, but think it could have been presented in a plot line that would have been absolutely stunning.
When I read the Author's Notes and found that his theories were completely plausible, I was disappointed that he didn't construct a more medically-complex thriller.

I kept seeing "The School of Night" by Louis Bayard in my book club magazine and always thought it looked really interesting, so while I'm in Elizabethan mode, I wanted to read it.
I recently finished "The Book of God and Physics" by Enrique Joven and enjoyed it. It's a book about the Voynich Manuscript which is a 15th century manuscript written in code that has never been deciphered.
The Voynich Manuscript and some of the same historical people are also mentioned in the book "Shadow of Night" by Deborah Harkness which is the second in the trilogy. It's mainly set in Elizabethan England. My sister gave it to me for a birthday present. Now I have to wait patiently for the final book.
