Royal Blood is a historical romance with a paranormal (vampire) twist, but the publisher (Kensignton) categorizes it as Historical Fiction. It is that too, but there is definitely a love story complete with sexual tension, a few hot bedroom scenes and an HEA. Most characters and events are from real-life, even the heroine. I really enjoyed it! It was a great read to savor, not devour. It is written using the period language (1500's, Tudor England), which may challenge some people. There are a lot of characters in this story too, but the story does spend most of the book focused on Renee and Michael. I loved it. The book is unlike Rona Sharon's previous novels. This is much more a classic literature read than a typical (and predictable) historical romance read. I love the new direction she has taken with her writing.
