Random.org. I then did a search on Goodreads using that keyword and chose the first ebook I found that I had on my TBR list. Complicated, but it did come up with something really random!
So, the keywords I had to choose from were: eternal, snowflake, dice, hope, luck, and castigator (yeah, I know - I actually used a random-word generator to select this one, just to have another word on the list). The one I ended up with was "hope", supplied by Junying Kirk. The first ebook I ran across in my search that I owned and had not already read was The Tragical History of Dr. Faustus by Christopher Marlowe, which I downloaded for my Nook in February of 2011 from ... somewhere. I didn't make a note of it. Before the end of November, I will try to get this book read and reviewed.
I hope you'll be looking forward to it as much as I am!
