Cover: It's a solid cover for the book. It makes me think of the cover for The Once and Future King. I am not sure if the "No King. No Rules." part is all that additive, but it's a minor point.
Synopsis: It's a good synopsis that clearly articulates what the book is and isn't. It's a play on a familiar tale. It'll go into a story that people know, but it will explore the characters in ways in which readers have not experienced before. It's a clever concept, and the writing in various characters' points of view makes for an interesting narrative construct.
