4+ Stars. It was a fine first novel and I enjoyed it. A bit too detailed in some places and scene breaks would have made it a smoother read, but historically correct for the most part.
It was a twist on the more popular idea of Emma being the beloved queen, however it is absolutely clear that Canute had feelings for both Aelfgifu of Northampton and Emma of Normandy. Later contemporary writings lean towards Emma but this version worked well.
I did enjoy Cnut's first wife's story and learning about her life. It was a very good representation of the history of that time which I always seek out to read. I am hoping Kelly Evans has another in the works.
