If you've read "Of Royal Descent", you need to read this book. It continues to develop the characters and Chuck as a zombie. I can't say too much about it or I will give away the story, but it does explain more about Doyle's relatives. I will say Doyle's sister is something special. I can't wait to read "Heir to the Crown" to learn more about his sister. I hope Ember Shane hurries up and gets the next one written.
