I am pretty picky on my kings and queens type of stories. This one seems right up my alley. Reminds me a bit of Stephen King's The Eyes of the Dragon. I did enjoy the dates in the beginning too. Theres a mystery element and a love element, I feel like anyone could enjoy this book.
That being said, I love the story of Robin Hood and would love to see the authors twist on it. I would definitely put this book up pretty high on my tbr to get to.
