The Last Kingdom, by Bernard Cornwell. Just because I've never read anything by him and it caught my attention.
If you enjoy The Last Kingdom as much as I did, you'll become a life-long Bernard Cornwell fan. My brother and my daughter recommended his books to me months and months ago. Finally, earlier this month I read The Last Kingdom, and immediately followed that up with the other 3 books in the series, then started on the 3-book Grail Quest series, and am now in book 3. Such great historical fiction!
