Just finished the new 3rd season of The Last Kingdom on Netflix.
I loved it
So did I! I loved it too. I believe there is a 4th season coming, but not for a couple of years. I plan on reading the books in the meantime.
I have a serious girl crush on Aethelflaed, Lady of the Mercians. The real Aethelflaed went on to achieve great things for a woman of her time, and ruled Mercia in her own right. I was very impressed with Alfred for having ensured that his daughter was as well educated as her brothers.
